Possible (in fact, I never knew about that facebook page before, so I wont agree or deny on it), but saying that most of those who ain't thinking the same way you do got that from that page is an insult, especially after you said it's a cesspool.
No. It's not an insult. That's like saying I'm insulting you by call it faux news. And it's not that they aren't thinking the same way. It's that they are spewing verifiable false rhetoric
