Well, it is not my fault your English is quite confusing. I am having a hard time understanding what you are trying to say from the beginning.
Also, since we are not acquaintance, I don't really know how literate or ignorant you are when you mention Kent and tell me to go read his books after I talked about Duchamp. You fail to make yourself clear. (Also, are you by any chance trying to refer to Kant?)
What I could notice is that you are quite presumptuous and seems to suffer from the condition that frequently makes people with artistic tendencies think they are better than other "ordinary and vulgar" human beings.
Because supposedly art is the highest form of human manifestation, artists, or merely people that like or understand about art should be some kind of special group above others.
As if people that create technology that saves lives and bring comfort or people that provide services are not often more impactful to humanity.
And that seems to be what entitles you to make a rude comment on someone else's opinion then quickly progress to personal attack by mocking their intelligence and maturity by calling them a child. That is certainly a very mature way of dealing with situations.
This is one of the most brainless things I have ever seen. Doesn't even make sense!
