“Then there's the matter of female suffrage. I really don't see how suggesting women should not have been granted the right to vote is misogyny."
I can’t see that it’s anything else.
Whatever it is that you find ‘wrong’ with women voters, you’re applying it prejudiciously against ALL women, and no men. That’s literally misogyny.
“It might be motivated by it, but not necessarily so,”
HOwever you get there, it’s misogyny.
“and treating it as such is akin to criminalizing holocaust denial:”
Calling it misogyny is not criminalizing the practice.
“it's censorship, pure and simple,”
There are consequences to saying stupid sexist things. That is not the same as censorship.
“and if /r/MR wants to keep calling itself an open space where ideas are not silenced, that attitude has to change.”
Calling out your misogyny is not stopping you from posting your misogyny.
And really, there are no legal requirements to BE an open space for one to call themselves an open space. It’s not like they’re subject to any ‘truth in advertising’ laws.
“I'll corroborate my claim with the writings of Laura Grace Robins, whose blog contains a whole category devoted to women's suffrage and how it has negatively impacted society.”
You have an opinion, and it’s a negative sexist generalization.
It doesn’t make it any less of a negative sexist generalization because one woman on the interwebs agrees with you.
“Whether or not you agree with her stance, you cannot claim it arises from hatred of women.”
Why the fuck not?
The assumption that a woman can’t hate all or most other women IS A SEXIST ASSUMPTION!
