I was raised on Fox as well, was even a founding member of my schools young conservative club. Global warming was actually one of the topics that broke me free of that bullshit mindset. I told a few friends global warming was bullshit and they were like “bro you’re dumb, here’s how we know it’s real.” I understood enough science to get it was happening as well as the implications. That got me questioning everything the news said, which had me coming to those same realizations you did.
