In reading your post I honestly first thought you were headed toward a different direction than you were. I don't applaud Spencer being punched- I'm against it. But I must admit that my addition, highlighted below, comes close to my own feelings about it.
1. Some person somewhere gets punched in the face - I yawn, there are a million of these every day. The fact that this guy belongs to group 3 below further dulls any outrage that I might have had.2. Some person somewhere gets shot and dies - I yawn, there are at least hundreds of these every day.
3. Some person mouths off about wanting to ethnically cleanse some country - I yawn, there are hordes of fanatical bigots in every country.
Fair enough. You don't need to feel outraged - I don't. Some posts just come too close to 'that's a bad thing, I sure hope it doesn't happen again - nudge nudge, wink wink' for my liking. That's what made me sit up and blink. For me it comes across as implied approval or even encouragement of the thug's actions. YMMV.
