I work in political communications/as a civics educator. I also grew up in a purple state in the 90s with a half liberal family and a half conservative one.
The media landscape is completely different now. When I was growing up, my dad and I would do things like listen to Limbaugh and then discuss what points we agreed with + how stuff was covered online (he read the Drudge Report and other conservative online news and I read the opposite).
One difference is that back then if I listened, I could get a genuine idea of what the other side wanted: Watching a liberal outlet would tell me, at least broadly, what conservatives wanted. (Fewer taxes, more religion, greater national security, etc.) Likewise for a conservative outlet re: liberals (Gay marriage, no war, etc.)
Now? The media is just constantly spouting things that are completely batshit.
