I see your point, and seems valid enough, except Greta put herself in the public eye, and by intent, whereas Baron did not.
Greta's entire puropse is to stir discussion by being confrontational, so what comes her way - even the lass savory stuff- comes with the package. (Not that that justifies the nature of some of that which is flung at her)
Baron is just a kid who had no choice or doing in his life circumstances. Targeting him is just crass and totally uncalled for and unnecessary.
