I wrote a comment about this question:
How to ask a man to not take up more than one seat on public transport while avoiding conflict?
I was basically reminding OP that not only men take extra space because OP's message was sexist. I think that sexism can be applied both ways and not only men against women.
I was just trying to say that OP's message was sexist against men and I was censored in a few minutes.
EDIT: a few minutes later, another comment asking OP to specify where they were in France, because in some places in Paris they could be beaten and answerers should know this, was also censored. Seriously guys! It was a serious life saving advice that OP should be aware of, and you guys just censored it?!
