Response to Gina's question:

Is it better to repress our emotions for the sake of societal standards, or should we express ourselves freely through the medium of art?


Well, we already express our explicit emotions in art as of now along with the past, and we do repress almost all of our emotions for the sake of society. But to choose which is better, I'd say, leave it the way it is now. People are very fragile beings that are very opinionated and prefer explicit things to be censored. I'll have to agree with that, after all, there are younger people/children who aren't mature enough, nor old enough, to hear or know of such emotions. It helps the way children grow up into when they become older. Those who are exposed to such explicitness would experience, for example, violence early in life.
To express our feelings and emotions in art is more of a safer way of expressing it than to just to tell people about it (then again that's why we have therapists to talk to about it). Through art, if you choose abstract art, you can hide those explicit thoughts in the painting or drawing or whatever art form it is you choose. So either way, we use art as a form of escape to express our hidden emotions.
