The point is to show their hypocrisy
I get that part and there's plenty of ways to do that (like the other examples linked to) but in the Kathy Griffin example I think it's a fail. When she did it it was intended to hurt Trump supporters and it was disturbing. I don't think there are enthusiastic Biden voters (archive.is), and most probably could give crap over memes like that, other than to use it to promote/spin their current narrative, which is to accuse Trump supporters of being domestic terrorists. For that reason it's not only ineffective, it's a losing move imho.
