I'd say its not only Linux community, but pretty much any community that has communication based on the Internet what makes people behave much worse than they mostly do in their 'real life'. However, there are communities that do care about this problem a bit more than others - if you're not treated well by Linux guys, there are other free operating systems like FreeBSD, NetBSD, OpenBSD and DragonFlyBSD, their userbase is smaller, so they actually care about bringing new people in. Linux is not the only nor the best OS choice out there! ;)
