Do you think he'd rather be remembered for his contribution to science, or for being 'persecuted by the government'? Personally, I expect it'd be the former.
I think it's useful to put things in perspective though... People fought in the war and DIED.
This is a bullshit argument, of course they knew what they were doing to him and why. They persecuted him with the intent to eradicate homosexual people. If you can give the Brits the benefit of doubt and assume that it wasnt clear to them how bad it was what they were doing to homosexuals, than you can equally claim that it wasnt so clear to the Nazis that it was bad what they were doing to the Jews. The persecution og the homosexual minority by the heterosexual majority is not less obviously wrong than the persecution of the black minority by the white majority or the persecution of the jew minority by the christian majority.
I'd argue that it was in fact the baddies that did this to him. The flag that injustice is committed under does not change the fact of the injustice.
