a conservative straw man and a vegan straw man

Hardly strawmen. The characterization of (some) conservatives was based (among other things) on the violence and harassment inflicted against LGBT people, while the vegan characterization was based on an essay I once read which made the Auschwitz / slaughterhouse comparison directly. (I'd give you the link, but it's in Finnish.) I'm also not entirely unsympathetic towards the view in that essay.

ETA: However, since it's obvious that the original wording is diverting attention from the actual point of the essay, I've edited that sentence. Instead of saying that gays shouldn't be killed, it now says "people are just saying that people shouldn’t be denied equal rights simply because of their sexual orientation."

Notice who's missing in his political universe? Libertarians

Giving examples in terms of every existing political group would have made the post unbearably long.
