That's been my mode of operation for a while.
In and before high school, before I came out of my shell and actually made friends with lots more people I liked and decided to try and become more open minded as time goes on throughout my life, I was kind of a bigot. An incel, even, because nobody really liked me and I was attention starved (which kinda fed back into it).
*shudder* I've had to learn that my younger days aren't representative of who I am now.
I know what it feels like. Some 4 or 5 years ago, I wasn't the best of people.
I bought into a lot of "le evil sjws" and "only two genders" narratives due to the circles I frequented. Most of it was due to me joining certain online circles when I was a timid introvert in a new school with no friends.
I said a lot of **** I regret and I might have hurt others aling the way as well. I try to forget that stuff but I think it's also important to remember that anyone can change.
Honestly, my irl friends took way too much of my bull**** but I'm glad they always called me out on it. It's part to them that I am who I am now.
The other parts would be me starting to listen to others and being more acceptive of concepts I didn't understand. If I didn't understand the point of something? So what? If it makes some people happy to identify that way, how does it harm me? And some of those things that I once didn't understand have now crossed my mind as genuine "what if I am like that?".
It was a process of unlearning and learning. Unlearning my internal bigotry and the fake narratives I was taught. And learning how to understand why others feel certain things make them feel good about themselves and why things I thought were inoffensive could be incredibly harmful.
Look back at your younger self and think of how much you've improved and how strong you'd punch that little ****head if you could go back in time.
