If you don't that kind of "modern art behaviour" you're probably intolerant. Don't worry, it's normal to be, we're all intolerant, but some act like they aren't. Anyway,
Once I started getting better and using the classic fundamentals to express my intolerant (by consequence. I can't help being intolerant if I have a soul) beliefs and thoughts, I realized that it works better than modern art in the end.
People will pretend you're insignificant and exclude you from social circles, but if you keep getting better and better, it'll become even harder for them to ignore you, and like-minded people will like your work.
tl;dr it's a waste of time to get angry at other people's bad taste. Just get better, complaining won't help. They won't change.
Once you get good enough you'll realize nobody can ever take that away from you. All you will ever need to provoke thoughts and crowds is a simple pen or pencil.
