One thing I've found is that pop music fans are generally very tolerant of other people's taste in music. But lots of people bash on pop music simply because they don't enjoy it. A lot of your complaints are subjective untrue. Most famous pop musicians went through puberty many many years ago. I still think Nicki Minaj is a good musician. Rock and roll used to be controversial too. Simple melodies don't equate to a bad song. Many pop stars donate money to charities. It sounds like you just don't like listening to pop music is fine, but don't make up fake reasons as to why it's bad.
