Most of the posts are just complaining about him losing the tournament, issues with how his relationship with Johnny is unfolding, or ranking him as leagues above the other student fighters.

And mercilessly lambasting Miguel over the school fight and making Robby out to be 100% blameless for everything except kicking Miguel over a railing. I believe Robby was the first one to exchange a verbal barb, wasn't he? He said, "You can't cheat your way out of this one!", yet people lambasted Miguel over bringing up Johnny and Sam.

News flash: Robby wasn't defending himself after Miguel let him go.

When Netflix's subtitles say, "[roars]", you can't cry self-defense anymore. Robby went on the offensive and made a mistake. Deal with it. The moment Miguel made the comment about Sam, I didn't see a single Miyagi-Do move come out of Robby. No blocks, just all-out-aggression.
