Yes, there are lots of nasty comments which should be reported. Personally I would like to see MN come down harder on racist and disablist comments. I realise modding is a hard and (for the most part) thankless task, but I think sometimes they let disablist and racist comments slip through under the guise of "the poster meant well, they just mis-spoke".
It's worth reflecting on why we have women's rights in addition to general human rights. Some of them redress historical imbalance (within my lifetime we've gained the equal pay act and seen the much-needed criminalisation of rape within marriage). But some of them refer to female biology - for instance legal protection against being sacked during pregnancy or against discrimination while breast feeding.
There is a small subset of rather vocal activists within the trans community (and I think it is a small subset) who take any sort of women's rights rooted in biology not to be protections afforded because of the specific life circumstances that come with female biology, but instead as a kind of affront to inclusivity. Thus, for example, female changing rooms become not places where women can change free from the male gaze and the threat of sexual harassment, but places of segregation akin to "whites only" bathrooms in 1950s America. I think the racial segregation analogy is a deeply flawed one (one only has to look at the campaign for women's public toilets in parts of rural India to see that this is actually one of those issues driven by the specific needs of being female - women are more at risk of being on the receiving end of sexual violence than men) but it's one which needs to be discussed openly, without twee euphemisms and obfusticating language.
I think it was the "no debate" hashtag which drew a lot of us to this - where changes to the existing legal framework protecting women's rights are up for grabs, the answer surely has to be "yes, we must debate - openly, honestly, without contrary views being shut down."
