Controversial opinion: Trump has frankly made EVERYONE a worse person except for those with genuinely ironclad principles.
So many people from across the political spectrum have only used his existence as an excuse to be a monster themselves, even as they posture and congratulate themselves on their "empathy" and "kindness". And then they whine and cry and wonder why the world has become so mean and cruel, while refusing to look in the mirror.
And frankly I think they prefer it this way, because they seem to view basic decorum and decency, two keystones of any civil society, as a deadweight or something that only applies in the "rules for thee, none for me" sort of way.
Frankly I think it doesn't matter whether they were made worse by him or just really were always this way on the inside, because either way their actions are what matter. It doesn't matter if you become cruel out of necessity or malice, it matters that you are cruel.
