The FOSS-only people remind me of vegans. Plenty are respectful. Other ones get in your face to tell you how much of a piece of shit you are.
@Elizafox Unfortunately it's not just vegans or FOSS people. Such individuals happen to be in all communities with "big ideas".
They may be right thousandfold, but they are such raging wankers about it, they alienate all their potential allies and recruits.
Unfortunately, this sometimes includes me as well.
