Nothing. Huntley doesn't deserve anything. Nothing it could ever do would be acceptable.
This is why you are contradicting yourself.
Not sure if it got answered upthread, apologies if it did, but if it's penises that's the problem, why no transwomen at all even if that bit is no more?
If Huntley says he is a woman, then if TWAW is true he is now a woman.
You are now saying you don't agree with self ID. So
If Huntley has his penis removed, then by your own reckoning, he is now a woman. But you are saying this is not the case. For him nothig is acceptable.
So the question then is, who IS acceptable to you in order to be 'accepted' as a woman.
The above murderer - no.
Another random murderer?
Rapists? What about rapists where there wasn't enough evidence to convict? Less than 1% of rapists get convicted. So are the 99% given a free pass with you?
Sex offenders?
Burglars?
Council Tax Avoiders?
Where is your line?
