The thing with "all lives" matter is the same than with "prolife". They claim one thing, their actions tell the opposite.

And when you start asking questions, they contradict themselves very quickly. Which sometimes can be fun or used against them. I mean, nothing is more interesting than asking a prolifer to give money for starving babies in africa. When they show the foetus pictures, you show them the skeletal children. Then, when they inevitably say "but this is not my responsibility!" to get away, you can point to them that they are campaigning so those "babies" can't be aborted and instead die of starvation and that the life of the foetus isn't their responsibility either, but they campaign anyway.

You won't get them to change opinion, of course, but they would feel uncomfortable as hell and you take from them the selfrighteus thing.

The fact is that all their rhetoric is just that, ways to justify their hate and feel good with themselves while being bad people. And that is why they are so angry at "woke" culture. Because "woke" people look down on them. And that is annoying for them.
