I look at it like a fisherman casting out his friend/enemy distinction bait, seeing who bites so they can reel them up and then decry them as friend or enemy. It's what most social media posting is, constant signaling of what tribe of interpretation one follows and either trying to get into a verbal fight or a verbal jerk-off.

Extra bonus points if they hook a racist and then they get to re-live the civil rights era for a state sanctioned 2 minutes hate.
