AITA?

Okay- for the context- I went to a bar with few friends and there was a group who was being super loud and I do not like loud people and also it was a bar for ffs!
Anyways- the group was of guys who seemed gay? and my friend said that she hates loud gays and I kind of understand the sentiment too cause I detest loud people in general but all my friends started attacking her and when I defended her called me and her homophobic.
Am I being homophobic..????
