Your previous comment implies the same. Regardless, I’m not saying that anyone who disagrees is necessarily, just observing that the natural consequence of said manipulation would be to hold a dogmatic insistence that “it’s them, not me”.
It's mis- or disinformation to say that all sides, all people are the same. It's the ultimate cover for people doing wrong - it eliminates any 'wrongness'.
A corrupt politician might say, 'everyone is corrupt'. Now their flaw is wiped away, in a relative sense. But it's not true.
