Haha yep! Bboy Dragon and Lopedo are two high level players that have been really rude to me personally. Like, sorry I have a life and a job guys lol...
Bboy isn't a high level player, lol. As for Lopedo, he's "always" an asshole online, literally. Can't take him seriously. What I will say though is those XBL kind are rude as fuck though.
Lopedo's an "intentional douche" from what I've experienced. That's just his persona. As for "rude high level players", most of them are likely not as "high level" as you think. Especially online. The real high level players are the ones you see dominating tournament events on a regular basis, whom also tend to be quite chill in person.
