WPUK decide who is an icon for them. They don't insist we must agree, they have no need to ask for permission. They share their appreciation for women they think made worthy contributions. That's it. You LassOfFyvie are free to take it or leave it.
As it isn't clear from my post, I'll rephrase:
Anyone who denies WPUK (and the gender critical in general) the right to post a tribute to a murdered woman who was raising her voice in one of the UK's most violent ongoing issues as well as an issue specific to lesbians because that woman disagreed with WPUK's position on a completely different issue, is purity policing.
Such people imply thereby that WPUK are only allowed to pay public tributes to women who agree with WPUK without facing criticism, a thoroughly objectionable position. It's also saying that they deserve the accusation that they could not possibly be posting this tribute in good faith, but seek to mock the person or to exploit their death and should have been silent instead lest they look discourteous or tactless.
That's a view I find reprehensible - one that says adversaries cannot honour and respect those who disagree with them without deserving criticism. It's basic human decency to share a community's sorrow at a person's death and to express appreciation for that person's contribution to society.
Whatever grieving friends and relatives may be thinking is anyone's guess. Their grief is their business, and whoever they want to be angry at, they will be angry at, however justified or irrational. That's what happens in bereavements. I've found irrational anger helpful. It was a welcome distraction from my grief. I'm not saying it's healthy or welcome or needed. It's just what happened to me.
I do know for a fact that if my adversaries posted a tribute on my death, my family would be saying - Look, even those bloody bastards have to acknowledge she did good (or some such) because that is precisely what I've seen them and many other people saying in connection to other deaths. And if not with appreciation, at the least such tributes were greeted with satisfaction.
