I must agree with the OP and I've had my LTC and been shooting for over 20 years now. I've never once had a problem with a person at any ranges or shops that I've gone to and in the last 8 months I've almost had to pay rent to the gun shops because I'm at them so much.
Around 8 months ago was when I found this site and I found it to be entertaining and helpful so I signed up. I kinda kept to myself until about a month ago and boy let me tell you people are in a whole different way when you're not face to face. The comradery goes away quite quickly when nestled away comfortably behind a keyboard.
I've had a couple of discussions on gun related bulletin boards, not only NES, the same basis of discussion which I've had in person with different people a hundred times turned into being personally threatened with physical harm just from standing my ground in a discussion. And it's not only me, I've read so many threads over the last couple of months where people get into huge arguments over the smallest things and yet they want to smash each others heads in. I can't help but to laugh at their mentality, or lack thereof, but it is pathetic and sad to watch two people who probably have so much in common yet they get angry so quick and resort to idle online threats.
These are the two things to look out for:
1) If you see someone blast someone for a) asking a "stupid" question (for the record no question is stupid unless it's already been answered 1,000,000 times (use the search function first)) or b) stating something which is either incorrect or someone perceives as incorrect and then the offending person will make arrogant remarks about how you are wrong and they are right. This is a person to stay away from. Just laugh at them and pay them no mind, they are only looking for attention. Do not give it to them and they will die.
2) Some people are just never wrong. If you try to help someone by kindly, and not in a demeaning way, point out an inaccuracy in someones post and then they blast you because their mommy taught them that whatever they say goes and they themselves are never wrong so therefore it is by default you who are wrong, this is the second type of offending person whom you should steer clear of.
For the most part if you follow those simple rules you should never have a problem with a gun person. We all have common interests and as different as some of us may be we are in so many more ways the same. So have fun, don't let my words discourage you in any way, they are not intended to. I only point out my only encounters which could in any way be considered negative between myself and a fellow gun owner.
Oh and one other thing. Don't forget to move your clocks ahead one hour this Saturday before you go to bed and also it is advised that you change the batteries in your smoke detectors each spring ahead (technically 2AM on March 10th, 2013) and fall back. (2AM on November 3rd, 2013) This has been a public service announcement. ©
