When someone tries so hard to prove that they’re not something (a coward, a racist, poor, lacks intelligence, etc.), it usually means they ARE that “something” and they’re only desperate to hide it! Because if they know themselves and know in their heart that they’re not, there’s no need to prove it to begin with. The truth is just there.
I’d be suspicious of anyone who panders, virtue signals, and bends over backwards in order to “prove” something.
With knowledge comes empowerment!
