“Not out of genuine fear of violence, but more as an escape from the smirks and side-eye I’d experienced in men’s toilets in the past. If I was going to make people uncomfortable in either room, the lesser disruption had seemed to be to go with female friends whose presence could reassure other women of my non-rapist credentials.”
So he wasn't scared of violence. He had the choice of either going in the women's toilet and making lots of women uncomfortable, and perhaps fearful, or being uncomfortable himself in the men's because he thought the other men might laugh at him. So being a complete self-centred arsehole, he chose to upset loads of women rather than be a bit uncomfortable himself.
Not surprised in the least. But the fact that he thinks this is 'lesser disruption'... He must think that 1 man is worth 10 or 20 women or something.
