It's absolutely not weird. Saying "I was wrong" is a signal that you can change your mind when given new evidence. If you don't signal this to other people, they will be really confused by your very contradictory opinions.

I own up because it helps me grow personally and professionally, and if I’m not growing, what am I even doing?

No, it’s not. Being willing to admit you were wrong is foundational if you ever plan on building on ideas. This was a galaxy brained take if I’ve ever seen one.

I think this is a terrible take. It is so intensely important that one can admit they were wrong when new information comes to light.

The opposite of that is sticking to your statements which is stubborn and foolhardy. Owning up to it is courageous.

Which actually lends me to respect politicians who do that, and instead ridicule people who post old videos of Joe Biden or Obama or Hillary Clinton mandating heterosexual couples. A virtuous person is also open to adapting their convictions continually based on present day evidence and arguments - what is science otherwise?
