Don't insult them because they discuss topics at a more basic level than you prefer. There's always going to be higher levels (e.g., youtuber A < youtuber B < reading a text book < taking a university course < getting a degree < conducting novel research < conducting novel research published in journal A < journal B < journal C), which may be better suited for different audiences. Landing in one versus the other doesn't make you (or the instructors) better or worse. It's silly to say that the one you happen to prefer is where "good math" is.
