Am I complaining too much?

Oh my god, are they that obnoxious? The regular scene in one of my classes has a whole group of girls chatting away, laughing loudly, and even playing music off their phones for everyone to suffer through. My sardonic comments complaining about this situation to my other classmates is seemingly just quiet enough to not be heard by the offenders, and something inside me just isn't prepared to tell them to stuff it. Maybe it's that I feel that the teacher should handle these miscreants, or that I think they should realize their own callousness and start to apologize profusely to the rest of the class. But of course this doesn't happen, and I seem to be forcing myself to be content with the relentless annoyance, rather than give the girls my opinion to their face. Some of my reasoning is that I don't want to be the asshole who spoils their social time, and some is that it's not worth the hassle. But it's this little part of complacence to let them be, and let them be obnoxious, that is scary to me because it could be indicitive of future meek actions. I hate that word by the way, 'meek', because it just sounds so...meek. But I refuse to let that happen. I will not be meek or weak or run over, I will stand up for my comfort and my wishes, and not cowardly stay silent in my discomfort to be loud or righteous. Next time they dare impose their slaps unto our non-consenting ears, I will stand up for the class and tell them to turn their damn devices off, shut up, or get their asses out of class. I will demand silence from them, and I will get silence from them. Or maybe it's not actually too annoying, I guess I can deal with it and not bother them...Ha. But what I can do is speak up for myself in a respectful yet forceful way. Which I will do.
