I notice that "scientist"--without an article in front of it--occurs several times in this thread.
Presumably those are the posts from Russians who are trying (and, it would seem, having some success!) to set Americans against each other.
Well played, товарищ!
Accusing people of being a Russian bot because they didn't write "climate scientist" when that was already understood to be the area of science they were discussing, is also a great way to pit Americans against each other.
Wait, are you a Russian bot too?
