Male classmates and their audacity

In my previous university, I was studying a subject where the majority of the class was made up of women. There were maybe 15 men in a class of 200. However, since starting my masters I am one of maybe 4 women (to be honest I have not seen everyone in my class because people don’t turn up to in-person classes). But the majority of the class are men. Here is something I noticed, my male classmates always talk over the professor or other students especially female students it doesn’t matter if it is a class online or in person, they are always talking over them, and it is not in a quiet voice. Oh no, they will speak out loud. It can be so irritating because I can't hear the professor and when I want to speak up in class there is always the chance of one of them speaking over me.

Obviously, online classes are always a bit of a mess because no one really knows what they are doing but when you have someone interrupt every minute to say something that is not relevant it gets to the point where I just exit the class because I am not learning anything. An example of this happened today. In our consultancy class, we were discussing the work we were doing in the seminar. One of the guys interrupted the professor and started to just talk over him. This would not be an issue if he raised his virtual hand (Microsoft teams) and then when the professor let him talk, he would talk. But no, he needed the answer now and this led to others doing the same thing. This also happens when another student is talking. I could be in the middle of my sentence and they will start talking over me.

Did they not teach them that it is rude to talk over people? I was thinking of sending out an email to my classmates (I am the class rep, so I am allowed to do that) and asking them to not talk in lectures because it is distracting others. I know that I am not the only person who finds this annoying. But am I being dramatic over this whole situation???
