I’ve seen a lot of, girls and women specifically online, claim they’re “soft-hearted” or “cute and kind” but be extremely racist, anti-even documented immigration, say that other cultures don’t deserve a home, and call trans people “not people”. And more.
It’s one of my rules of thumb for life that people never state the obvious, except about the weather. People who are soft-hearted, cute and kind never have to say it, because they show it by being soft-hearted, cute and kind. The only reason to say it is because it’s not obvious (read: not actually true). It saves a lot of time and grief once you realize the pattern, because you can cut such people out of your life when they make the claim rather than wait to find out the truth.
As to why people are hard-hearted, ugly and mean, well, best explanation that I’ve heard is that it’s due to a deep self-hatred and fear of not being good enough, so they constantly need to tear other people down so that they can feel like they’re better than somebody.
