I've thought a lot about the logic of r63ing.
Like, in middle school, I had a friend that was a real dick, but he was downright hateful towards women. While I dislike him in retrospect, what I did with him strongly affected who I became.
In high school, one of my best friends was a lesbian. Would she have been attracted to me? That would've vastly changed our dynamic.(probably not because I'm not very attractive) I'm still among the group of friends I met through her, and I'm roommates with two of them.
A lot of people feared me in high school because I was large and I had a beard, so I never had to deal with bullies. would r63 me be a radically different person if she had been?
As long as we're switching things up, would it mean my mom died instead of my dad? His decisions vs hers would have huge effects on my late teens and early 20s.
I initially got into video games via Starcraft, which I only played at first because I thought Sarah Kerrigan was hot. If r63 me is also straight, would she not have played video games at all?
There are so very many stimuli in so many stages that go into forming a person's personality and circumstances. I have a feeling that if I had been born female, that person would be unrecognizable.
Also, my beard is one of my defining features, and I'm almost unrecognizable on the rare occasions that I shave it off. I have NO clue what she would look like.
