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.
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)
