While I agree a suspension is way out of line, as a parent who navigates the "anti-bullying" policies that schools put into place, I do *understand* how they arrived at their reaction. It all comes down to this bit:

“Wesley posted some very inappropriate tweets about the Heights athletic teams, aggressively disrespecting many athletes,” wrote Assistant Principal Monique Arndt. “After reading the tweets and taking statements from other students it was found that Wesley acted to incite the majority of our Heights athletes.”

If he deliberately talked trash about the players to piss them off, they gotta count that as bullying because he did it to them/publicly. It's one thing to talk to your friends about how your QB sucks, but it's another to shout "hey jones, you throw a pass like my grandma!" to the QB in the hall so that everyone else can go "boo to you jones!" and "yeah, you suck jones!". Is the latter bullying? In my world, no, because Jones should stop sucking at QB or suck it up if he does. but technically, yeah, it is - if you disrespect someone, on purpose in order to incite them, in a public environment so that others can join in the disrespecting ... that's what bullying is nowadays.

Would you think about it differently if he had tweeted something derogatory about a chick? If he had tweeted that the homecoming queen was as ugly as phylis diller or something? Or that she was as fat as X's mascot? Most people would. (not, mind you, that a suspension would be warranted in any case, but the *perception* of it would change.) And it's the same thing.

The difficulty kids today seem to have is navigating the fact that social media is public. And there are consequences to being an ass in public.
