I was extremely politically aware when I was 20. I was involved in activism and political organizations and all that stuff.
And that's where I met the leftists, and like every leftist, I found them extremely annoying. So no more political activism for me now, just... you know, voting the right way and getting into the occassional argument with fashy friends and family, like normal people do.
I see your point, though. People tend to think nobody gets convinced of anything because they are set in their ways, but the normies just get the vaguest echoes and politically active people just don't get a good view of what's going on.
