You have a lot of options. Reddit, Twitter, (far-)right Lemmy instances like bakchodi.org and wolfballs.
When I considered myself a communist (17 year old me) I thought opposing views really changed my mind.
When I was a 17 year old I was a complete pro USA centre-rightist that believed in heavily conservative Republican/Taliban views of women and who took pride in eating the new McDonalds burger on the menu. I believed in having a nice Instagram profile (which I never worked on) and believed Reddit was the frontpage encyclopedia of internet. I believed in a load of horseshit things like capitalism is a great thing for the world. Turns out, I am no longer 17, and we all change. Now I am a privacy advocate who also advocates critical thinking, attempts to bust lies wherever possible, and am far-left leaning, because I see the duopoly of liberal centrism and rightwing in a capitalist framework as the true cause of society’s exploitation and downfall.
