I think it’s a healthy thing to do to admit when your wrong as it places importance on truth rather than self image.
Some examples:
I thought pay-per-view was paper-view because you had to fill out a form to watch it.
This morning I insisted there was a noise outside to my partner and it was in fact the refrigerant in the fridge gurgling.
I thought the cat wanted to be pet— it did not.
Oh goodness, 24 years ago I was uninformed, narrowminded and had been brought up sheltered and rather conservative. So I used to be hugely trans- and homophobic. I wasn’t actively hurting or confronting anyone, but I was definitely a big part of the problem.
It actually was webcomics that deprogrammed me. That showed me a world I simply did not know but quickly felt empathy for. Those were normal, lovely people who simply existed differently from me, they weren’t a threat and they had so many struggles pushed on them only for being different.
Today I’m far-left, progressive, super empathetic, happy that a lesbian friend calls me “one of the good ones” and that I, as a huuuuuge white cis guy, can be an ally and create a safe space around me for everyone who needs it.
When I was a kid, I disliked trans people for the sole reason that as a biological woman I get periods and they didn’t, so my dumb shit brain thought they had it better.
I was also against gay people, but mostly because fortunately the people I were around were accepting people.
At least I had the excuse of being an insecure child; I can’t understand why some people are so hateful as adults though (I mean I never denied that I can also be hateful but at least I judge people based on moral principles and not BS)
