Nonsense. It's already making a difference.
And nobody talks about the issues you raised anymore if there's any chance of them being challenged.
That's because of people like us.
It’s not nonsense, maybe you don’t have the same circle of family/friends that I do, but I hear those issues re-raised all the time. At least 3 of my more liberal Facebook friends posted the picture of this kid “taunting & smirking at” the poor Native American Vet. The MAGA hat just sent them over the crazy edge and I doubt they’ll admit they were wrong, since their truth isn’t based in fact, it’s based in feelings.
People like us might make a difference in some ways, but not with these people.
