Regardless of whether she's right or wrong, whether I'm right or wrong, on this issue, that's a disgusting way to behave and those little shits should be ashamed of themselves for stifling legitimate debate and discussion from a different marginalised perspective.
For the record, I am completely pro-trans rights and I think Julie Bindel is on the wrong side of history. But I also think that there is a serious conversation about safe spaces for cis-gendered women to be had. I disagree with her but she's a serious journalist and a serious feminist and the only way to work through this serious issue is by talking, not dicking about on the stairs like aggressive 8 year olds trying to bully their siblings.
