It would be nice if race would stop taking over random words.
Totally agree with you here.

^ That's what every one of my dictionaries say as well. There's a specific reference to a group of bandits, and then there's a general reference to a ruffian, criminal, etc. So if someone is using it in a racially charged way, that's their problem.
Admittedly, it's looking like the police involved in the arrest of Freddie Gray deserve the word "thugs" more than anyone in this situation (not that I would expect that use to escape charges of racism either). "Thug" is probably not the best term for the violent rioters and looters. Call them cruel opportunistic idiot neighborhood-killers.
(Yes, that phrase could apply to many politicians and powers that be as well. But if someone comes up to a person in a coma to slit their throat, that would be murder, not heroism, even if it's to make a point. It's much harder to build up than to destroy, so wanton destruction doesn't solve anything even if it draws attention. Burning the village in order to save it has always been b.s.)
