You idiots with "if you don't like a bit of a laff, piss off". I do like a bit of a laugh, but at funny things. If you're paranoid about the poofters and what happens when you bend over for the soap, just go watch a few re-runs of Benny Hill. I'd rather have a laugh at something that's actually humorous.
"A man should apologise for the actions of his grandfather oppressing his grandmother, but his sister (also a grand-descendant) has no case to answer. This argument is ridiculous but it's used 50 times a day by feminists."
Here we go. We talk about one oppressed group of people, and suddenly it's all about the evil feminazis. Give it a bloody rest. No, men should be *doing something about* the *continued* screwed-up gender inequalities still going on today, not just wahing on about poor didums granddad being called out as an oppressive old bugger who kept grandma under his thumb all her life. In that "example", it wasn't grandma acting as a right turd who expected instant obedience at all times, or who denied granddad the right to his own money, his own property and his own job.
I actually don't want any men today to apologise for what granddad did, I want them to acknowledge it was f#cked up then, and, moving on, that they want to interact with women as equals in this day and age.
As for apologies, I think they're meaningful inasmuch they are a signal that things are going to improve. So, with apologies to Australian Aboriginals and the like, it should be about "We are sorry for the crap our previous governments visited upon your people, and the fact that today we still benefit from the genocide and forcible confiscation of your land today [because, hello, who owned all that land that those lovely ore mines are sitting on now]. Here are some things we want to do to make restitution..."
To apologise to Turing would be odd - he's dead, duh - and to gay men who were persecuted at the time. So they were, and while prejudice exists still in the UK, it's more at the individual rather than the institutional level. So an apology wouldn't not really be a signal of restitution - the hard work's been done already with the law changes since the late 60s.
