Because part of feminism is thinking and talking about male violence against women and girls.
Because we already talked about this man, when he was undermining boundaries by indecent exposure. That's a pedestrian, common or garden paraphilia (flashing) and a sex crime that often is a red flag for worse behaviour (see Wayne Couzens).
Because transvestic fetishism was also classed as a paraphilia until a few years ago in the medical literature.
Because this man has been supported, feted and ultimately enabled by the establishment. The government and the.media celebrate this.
