Just caught him being interviewed on Jeremy Vine's radio 2 show (ugh.) I wasn't listening at all but it got my attention when he mentioned 'trans rights and t**fs and so on' or something similar.
I gather he's promoting his new book, 'Elizabethans' which is about Britain since the early 50s when the current Queen came to the throne. His point about trans rights was kind of tacked onto BLM and he seemed to be saying that many of the current social media arguments are not new. That people have been fighting for better treatment on the grounds of race or sexuality for decades. He mentioned one of the Monty Python actors coming out as gay live on TV (the first person to do so.)
I wish I'd been listening more closely, and hopefully I've got this wrong and Andrew Marr - who is usually a sane and sensible commentator - doesn't conflate 'gender identity' with sexual orientation. Does anyone know how the book tackles this subject?
