Sometimes I really don't understand why so many CS students take pride in talking in a highly disrespectful manner about their professors. While it is true that not all professors are upto the mark, but imo that still is no reason to use derogatory language for someone senior to you, which sadly is quite common these days.

some people are just mentally capped and try-hard to meme everyone around them for personal internet gain aka e-peepee.

One thing I learned in the military is that respect has to be earned. It applies to the professional and academic world as well. You can’t just expect someone senior to you to be respected. A professors would have to earn respect by their effectiveness to teach and grade fairly, and most disrespect I’ve had or encountered for professors stemmed from that. As professors they should be out to improve their knowledge as well as expanding their student’s knowledge. If they’re being derogatory just to be derogatory then that just reflects on them as a person, and shows they’re a terrible human being. Now if a professor doesn’t really know what he’s teaching and acts like he’s making it up as he goes along while poorly summarizing a text he glanced over then he or she probably won’t be respected by the students he or she teaches. Especially if they don’t have any real world experience programming or web development and are now teaching a web development course.

Might be some cultural and economic differences. Here in the US at least, there isn't as much of the "show deference to others just because of their station" especially to professors who you are paying tens of thousands of dollars to learn from but clearly don't know their shit.
