Kathleen Stock, a feminist English philosopher and outspoken defender of sex-based rights and reality, visited the Oxford Union today despite efforts from trans activists to deter her.

The Telegraph reports that hundreds of trans activists “commenced a march on the Oxford Union, chanting ‘cut your system, f*** your hate, we are not open for debate.’” One trans activist, wearing a T-shirt with the words “No More Dead Trans Kids,” even glued herself to the floor in front of Stock and the president of the Oxford Union Matthew Dick.

In a recent TV interview on Good Morning Britain, Stock gave an eloquent explanation of why it’s wrong to stifle views simply because some people find them upsetting.
