Dayum.
These antivaxxers have one thing in common, don't they? They publish their little memes on FB, and they share them, and copy them, and then accuse us on the Left of being sheep.
Seriously? Nobody does "following, copying, sharing and using unoriginal material" better than these damned antivaxxers. They have nothing new to say themselves so they share all the BS that someone else (months, if not years ago) dreamed up.
But we're the sheep?
You nailed it. It's clear projection.
