Yep, dinosaurs are either fake or became extinct a few thousand years ago,
I've come across a few people who believe exactly that.
I smile. I go my way, they go theirs, and I don't meet another of that kind or hear any of that nonsense for years.
There are those who insist on equally spurious claims of "climate change" and "men can be women."
I hear about or notice the climate and gender claims every single day. The barrage is nearly inescapable.
Both of these kinds of critters have the potential to become equally dangerous to those who disagree, or simply want to be left alone to their own beliefs.
My belief is that the climate and gender lunatics are currently infinitely more dangerous than the creationist crusaders.
All other things being equal, I can't decide which side is worse.
