I agree but I don't think it's been amplified, I think what happened is that we've become aware of it's existence. Previously we'd conceptualise this type of behaviour in people in another way - like the guy's just an a-hole. Now we know that something very deeply psychological is going on. We know it can be societal. We know these people vampire off other people's energies, and are by default malicious and deceptive. We know they struggle with empathy and can do the most damaging things to people for no reason other than some power buzz they get out of it.
Here's me reflecting over decades, recalling all the idiots from our own community who used to say this type of stuff didn't happen, or was exaggerated.
All the 'sianay' who called people highlighting this stuff, 'trouble makers'.
All the daft thirsty apneean who thought Sikh blokes telling them about these people were lying.
I guess some progress has been made.
