One of the fundamental rules of credible arguments is, ‘’He who makes the claim provides the facts’’
If you say something, you need to back it up. As pp have said, if you were that confident in your convictions, you would have absolutely no issue with providing references.
‘’Do your own research’’ is just a tired old line. The second I see that I immediately know that the person is a gullible idiot who likes to think they are intelligent.
It’s very entertaining to watch, actually. I’ve got my conspiracy theorist bingo card at the ready 🤣
