Legal definition of rape:
Rapeis astatutoryoffence in England and Wales. According to thelaw,rape occurs when one person penetrates another with their penis without the consent of the person being penetrated. If a victim is forcefully penetrated with an object, this is classed as "Assault by Penetration"
Saying that there are other forms of violence in prison does not justify giving a known rapist access to females - it's just 'whataboutery' and is nothing to do with the OP's question. My view is that this person used the confusion about transgenderism to gain access to vulnerable women who had no choice about him being there, could not get away because they were locked up with him, had to shower with him etc etc. The prison service is getting itself in a complete knot about this, as are so many other organisations, and the result is damage to women and women's rights. By the way, he also said that he would, and could, abuse children and think nothing of it. That's maybe not relevant to this thread, but he really is a very dangerous person and should, in my view, be kept as isolated as possible.
