That's 28 trans people dead by homicide in total. Again, including gang and drug activity, and domestic violence.
The "just for being gay" bit is open to debate, and should be met with some skepticism considering the "just for being trans" and "trans genocide" thing includes so many PSGWSP situations that very clearly aren't "just for being x" (not excusing the 1 or 2 "trans panic" murders each year - they are murders, but that's a pretty easy death to avoid). Conservative estimate is 12.5m gay people and 1.8m trans people, in a nation of a little over 320m. If we believe the inflated/likely-lies 80 people then you're talking about really low odds, and I see a lot of killings by parents, religious groups, gangs, and mean teenagers. Show me some data; if the threat is alt-right Trump supporters, it's bound to be there. And no weasel words or rat stats, thanks.
I guess when I'm at a mostly-gay casual bowling league and there's a previously quite calm trans woman now illegally concealing a no-joke sword and ranting because of "Trumpanzees and Alt-Rights" (asked to leave; refused to put the sword in her car - they do allow lawful concealed or open firearm/knife carry), and a previously intelligent and collected programmer who is living in fear of "Trump's gay internment camps" and is driving his husband nuts about moving to Canada, their well-paying jobs be damned, my first question is "Why do you believe this?" and if the answer is "The gay rights group told me so and the media did too" with literally zero data to back it up (other than the toothless gumflapping of some irrelevant 80s white nationalist, or an early 2000s Pence campaign site quote taken out of context), I say "**** that group".
Especially if such groups are the first to defend other groups/people/ideologies who HAVE actually executed mass shootings and murders of gay people "just for being gay" ala the Pulse night club or countries like Saudi, Qatar, the UAE, etc, and even celebrate Iran for their "progressive stance on transgenderism" as they horsewhip or kill men for kissing. You want to toss around the term "genocide" with regards to LGBT folks maybe look at Chechnya or Uganda, not the US. But instead it's a political drive for political organizations that have nothing to do with civil rights, unless it's restricting them for others. I just thought Pink Pistols was better than that based on my experiences with the Boston chapter.
I think there are a couple things going on here at the same time.
To start, I agree with your premise that a so-called "gay genocide" almost certainly doesn't exist. I want to be clear - I personally disagree vehemently with the concept of "hate speech/crime" laws. In the cases where these behaviors rise to the level of crime, we already have laws; and if you have enough information to prove motive, the act is probably foul enough that we have other modifiers to apply that have [more] objective standards of proof.
Next, the documentary in the article in the OP is written by an Australian, interviewing Californians. I'm not saying there's bias there...oh wait, I absolutely am. Just as there are crazy mouth-breathers on the right, there are also whackadoo neckbeards on the left. It turns out that stuff sells newspapers. And before we blame this on the millennials, yellow journalism dates to at least the 1920s. Hell, actual journalists were publishing stories about Spring-Heeled Jack in the late 19th, so we're well over a century of "fake news." None of this should be surprising.
I have the particular pleasure of spending most of my internet comms time here, while the majority of my meatspace existence is among educated Cantabrigians. This means that I get to hear about "Trumpettes" at least as often as "Snowflakes." Truth is, we are all blind to our own hypocrisy, and find it terribly hard to see the world outside our experience. Facebook and the spin of Fox/CNN/MSNBC/Breitbart etc. make it really easy for us all to create ideological echo chambers that reinforce our preconceived notions. The human animal wants to minimize effort in order to maximize the energy available for survival, so we create these shelters. There are very few of us who actually engage when those obviously misguided statements are being made.
Now, to the topic of the Pink Pistols specifically. The simple reality there is that, from a legal perspective, we don't exist. There is no monolithic Pink Pistols organization. We don't pay dues; we don't maintain membership rolls. We are a movement that holds a singular stance - all people are born with the right to protect themselves. We are centered inside the LGBTQ community because there is a history of violence in and against that community that we believe we can help minimize. While there is a person who holds the title "First Speaker" there is little she can do to affect the behavior of members elsewhere, and even less to control their messaging when they choose to take an interview.
I should be clear, while I hate the rhetoric and bombast that gives us the current state of political "discourse," I must reiterate - identity-based violence does exist. It doesn't always result in death, but then most violence doesn't. That doesn't change that I, and people I care about, have experienced harassment, assault, and physical attacks for the clothes we were wearing, the clubs we were leaving, and vocalized assumptions about who/what that made us. This includes here in Boston, in the 2000s, and specifically since the 2016 election.
None of this is Trump's fault, but explaining that requires getting people past the handwringing and into a place where they can feel safe having these conversations. It sounds like you're trying to do this with your friends; I'm doing it with mine. Let's not shoot the messenger here. In between the Aussie shenanigans is the good news - people in the queer community are getting armed. This means that - at least on this topic - they're breaking free of the issue-bundling that comes with the "two-party system." The best thing any of us can do is extend olive branches, and try to tear down some walls.
Maybe then we can "progress" towards actual freedom. You know, the laissez faire kind where we stay out of everyone else's business as long as they're not hurting anyone.
