As a bisexual woman I sincerely hope he stands his ground and that more do, too. I went to a national trust place a few weeks ago and there were bloody rainbow lanyards everywhere. It's all just paying lip service to diversity without any genuine shits about those of us who aren't heterosexual, and anyway, the whole rainbow Pride thing has been co-opted by woman-hating arseholes.
I am sad for the humble rainbow TBH, it never asked to be appropriated for this political bullshit.
