"The man was an unrepentant bigot."
So was my granddad.
Sir Patrick Moore was 89 years old. Like my granddad, he was born and raised at a time when wives really did stay at home. (They didn't have much choice: we still had outdoor toilets and mangles back then; many homes either still had gas lighting, or had to plug their very few appliances into electric light fittings as there was no standard for wall sockets at the time.)
It wasn't until the 1950s that society started to move towards greater equality in the workplace. Even today, there are still issues of pay equality.
Furthermore, Sir Patrick Moore served in the RAF during WW2. He lived through six years of relentless wartime anti-German propaganda, found the love of his life killed by enemy bombing raids, saw his brothers in arms killed in action and was also shot down himself. You do not get to demand he switches instantly from anti-German to pro-German overnight on VE day.
Individual mental injuries take an entire lifetime, and may never heal entirely. Socio-cultural traumas on that scale take generations to heal. (Why do you think insulting the French is such a British tradition?)
VE Day marked the end of the fighting, but not the damage it caused. Wars do not end when the bullets stop flying. For many, the nightmares continue for the rest of their lives. We have a convenient label for this now: PTSD. And every war we've been involved in since WW2 has produced its own PTSD-suffering walking wounded. Their damage is inside, invisible to the naked eye. But it is there nonetheless.
You'd think we'd have learned this as a society by now, but no. We still get ignorant posts like yours.
