if you're very passionate about something it's easy to use strong words, and i think while it's annoying to me it's generally acceptable if used like this. I can't personally develop any strong feelings about vegetarianism or veganism, but I've had my passionate political moments in my life (and still do sometimes) and I guess it's kind of respect worthy, at least when I myself can see the logic of the argument or even agree to an extent.

Used to be I would get pretty frenzied when confronted with what I could fathom about capitalism, so I can empathize.
