It seems like at least half of what everyone consumes in all of 'social media' is 'politicized' but no one is interested in debating. Debating would have to mean we're talking to those gross people from the opposite 'team,' asking them to justify the policy they are advocating for, listening to them, and trying to convince them of our own positions.
When was the last time we witnessed any politicians or activists trying to change minds? Right-wingers scream dumb slogans like "They're sending the rapists over here!" and left-wingers scream back their own dumb lines like "Racist! America was built by immigrants!" And both sides dismiss the other side's arguments as the nonsensical ravings of the evil and/or stupid.
