Yeah, all that stuff depends where you are located. Up here in Vancouver amateur radio community, any kind of bigoted/discriminatory/exclusionary crap is totally not accepted or tolerated. There are always people experimenting with new things, sharing knowledge/experience, helping each other out. Heck, I built a portable radio pack and made a blog post about it, and my local club included my post (with my permission) in their monthly newsletter. I've also contributed photos to them and attended numerous community events -- always 100% welcoming and there's a strong educational/sharing vibe to all their events. When I hear people complaining about "hams" I'm always thankful to have seen almost none of this stuff locally.
