Source is Guido Fawkes, notorious right-wing moron.
Later posts by OP cite Lib Dems LGBT unit talking about... nothing to do with Huntley. All to do with being respectful to trans people.
It is astonishing that some people are falling for this nonsense. The Huntley transgender story is from the Star years ago still being perpetuated and there is nothing current to suggest that Huntley identifies as a woman or wants to be moved to a women's prison.
Twitter is against hate speech including transphobia, and that includes reports of transphobia about a criminal. It's not a binary system. They need to act on all such reports even if the foundation of them turns out to be untrue.
It is really gross how many people seem not to care about the rule of law in the UK. The criminal is receiving his punishment for his horrific crime. What you want to do to him is just disgusting and cringeworthy. Your revenge fantasies belong in your head.
