I feel the community at large is welcoming. There are a lot of people i have met that love to share knowledge and experiences. Especially to help new people.
I will say that there are several things that happen that can make some individuals seem abrasive. One is a combination of two things, being some folks just don't do well expressing opinions in writing, and others read things that have been written and attribute malice when there was no intent. Both of these cases can lead to misunderstandings and hurt feelings.
Another issue is that some people (including myself on occasion) have decades of experience, correct someone who is simply mistaken, and then the thread turns into a shit-show because ego starts to kick in.
That said, i feel like those instances are far and few between. I also know for a fact that several members here argue like they hate each other, but are literally friends and spend social time together in person. (This applies to me and a small group here, too) So, not everything here is as it seems.
So, generally speaking, I think GMRS operators and the community at large are welcoming and friendly.
I would hope money isn't the only reason. I have seen Rich be very forgiving to people on all sides, paid members and free members. That said, if there truly is a problem with someone, paid member or not, I think there should be some grace... but if it's not resolved, definitely let them go after a few attempts.
