At communion time, the ones who did not kneel or put out their hands were not reprimanded and the priest did not order them to receive on the tongue - he simply replaced the Host in the ciborium, blessed them instead of communicating them, and then communicated the next person.
A grown man who sees what Mass he's at and challenges the priest by ignoring the rubrics knows what he's doing. He's trying to start trouble like this clown.

Unless you’re deaf, I don’t see how one wouldn’t know it was a Latin Mass by the time communion rolls around. This man was most likely trying to cause a ruckus because of opposition to the Church or the Latin Mass. Of course, there’s the very slight possibility that he’s without an agenda and simply mentally disturbed.
Starting trouble...that’s exactly what he was doing. No sense of humility or respect. I attended a Latin Mass for years and we usually only saw confused persons at Christmas and Easter. They certainly didn’t pull the focus away from the Lord and toward themselves, thanks be to God.
