I should sound at least a note of caution, though.
By sexual perversion
Harris obviously meant homo-erotic activity and this from a man who enjoyed seducing teen-aged girls. When he declared this one a pithecine,
or that one a common scoundrel, I may accept his judgement but a voice of moral authority Frank Harris was not. His treatment of Wilde is available at Project Gutenberg
, by the way. I found it surprisingly well written.
Today, it's not such a big deal, but within living memory it was illegal to be actively homosexual and ruinous to be discovered as such. Yet, isn't it also true that a large element of HM civil service is gay? I remember British friends mentioning this about Sir Humphrey Appleby, when they learned I'd seen Yes, Minister.
If there was a sizeable number of gay civil servants, there might also exist a relatively powerful network of mutual aid and protection shielding its members from public scrutiny, one that has been successfully doing so for a very long time. It isn't so much conspiracy, in the usual sense, so much as a matter of survival. Given the cruel persecution they faced, who could blame them?
The problem is that such a network might be abused to shield most any behaviour, however noxious, and slippery slopes can get steeper when you're already beyond the law and the prophets.
