My first election out of high school I voted for a right wing candidate because that's what my Dad voted for, but also because I was entrenched in Christian ideaology and patriarchal propoganda.
After that I started paying a bit more attention to politics and slowly moved to the left with a few leaps along the way. Nowadays I find the Labor party of Aus to be about as conservative as I can stand. I can barely hide my disgust with anything to the right of them.
Real life experience can be far more radicalising than any immature ideas you inherent in high school.
Edit: My major leaps were: Having an employer illegally underpay me, seeing my friends lose 'stable' jobs in 2008, having a close friend come out as gay, leaving the church, volunteering with unhoused people, living in the UK, living in a rental controlled by a landlord with over 100 properties, and doing disaster relief work.
I love this shit. They're always so wrong but such fun designs. I wish I could find pictures of the old PS3 and Xbox 720 concepts that people were paying back in the day.
