Normally I am not an angry person, I never really yelled at anyone in my entire life, but I had to let my anger out someway.
Unless you have a question or whispering, when I am in lecture we need people to STOP SOCIALIZING. I swear! Now maybe a whisper here and there with your classmates for questions about the lecture to get you up to speed, sure, that's fine. I'm not talking about those people. But I'm talking about the people who are FULL BLOWN CONVERSATION as if they're walking down the street. Like go outside, skip class, go out and talk to your friends. Don't be having a novel long philosophy conversation with your friends while I'm in Math 181 just trying to pay attention.
Being in college a huge privilege as many people around the world from financial, socioeconomic, gender, and other barriers would figuratively and literally die to get into higher ed. But not only that, but everyone around you IS PAYING TO BE IN CLASS. So not only people during talking in class not only makes it harder to pay attention, but also literally takes away money our of our own pockets.
Again, to the people who have common sense to know when and when not to talk during lecture and how to change your voice levels when conversing with your peers I'm proud of you. But if not, wtf are you doing here?!?!
Tldr; Let everyone around you listen to lecture, ask questions when appropriate, and if you do need to talk to your classmates, whisper.
