Showing some discretion isn't about 2a, it's part of life. The idea that there is "can do" and "should do" can and should be applied everywhere. We can genetically alter humans, but we definitely should not, you can yell racist slurs but you should not. It's not a 2a concept. It's about being a reasonable person. One of the biggest reasons laws even exist is because people fail to restrain themselves from doing things they shouldn't, so the easiest way to get more laws is to be unreasonable.
So go ahead and open carry in a time and manner you normally would, but if you're going out of you way to stir things up by where and how (i.e. rifle at the low ready, or on a single point) then you should expect to get what you are after, a bad reaction. This is not seeking "normalization", this is kicking the hornet's nest.
If you're after normalization, start with an organized group, publicize it so there is no surprise or shock. Dress conservatively, no camo or tac gear. Be polite and show yourselves as "reasonable" people. And keeps those firearm holstered and slung, as if you are casually walking down the street, not getting ready for a conflict. That's normalization.
Oh, and for those that don't get it, I'm not quoting or replying to any specific post. It is as it's written, a stand alone statement.
