I have some sympathy with the post of A-H (apart from the Jimmy Saville bit) as "at that time", Turung was a criminal who flouted the law as, whether you like it or not, homosexuality was a crime.
Poofters, shirt lifters, queers, homos were in the 40's and 50's commonly used terms for homosexuals. he went to jail, he was castrated...AT TIME. he was treated NORMALLY for homosexuals, AT THAT TIME.
All ABers of my vintage will know this and all one can do is to play the cards that ones is dealt and homosexuality was not accepted and indeed was illegal........ they were the cards that were dealt.
Turing has been pardoned......and rightly so.
I would support the choice of Turing on a £50 note and I understand the post of A-H.
