Let's start with religion, which used to be something I held on since... birth, I think, as I was raised by a very religious dad. Weirdly enough for a south american he isn't catholic, but he is still a christian. I don't believe in that stuff anymore.
With religion came intolerance against the LGBTQ+ (and negating being bisexual myself until... last year?), and acceptance was something that actually took me time, especially with trans and non-binary ppl.
My politic leaning went from far right, to far left, to centre with something more in the left which is where I'm now I think.
I also used to be more of a pacifist, but honestly there are people who have to be shot at for them to listen. Just to be clear I'm talking about protests like what happened in Chile before the pandemic started, and not about literally shooting someone.
I also thought justice and police force were the ones to deal with crime, but now I'm up to defend anyone who dares to pull out a Batman.
I used to like chemistry and now I hate it, just as I used to dislike music and now I like it but not enough for me to put some time on it.
