Well, at least "mugged" is the word media outlets are using. In actuality, he just had his MAGA hat stolen from him, after he relinquished it after the robber informed him he had a knife. I personally reserve the term for when you are beaten up or at least robbed of your wallet, but reasonable minds could differ.

I guess it turns out that, just like you wouldn't go to UK and wear a "Britain First" hat, to France and wear a "National Front" hat, or to Germany and wear a National Socialist hat, you probably shouldn't go to a US city and arbitrarily wear merchandise of the most embarrassing piece of shit in our country's history.
