Art is to be enjoyed, not hated, there are as many opinions in this world as there are people, it's pointless to try and change someone's opinion about something.
Art is Art, and it's meant to be enjoyed, if you don't like a peice of artwork, the most respectful thing to do is just not look at it anymore and go seek out peices that you enjoy, people make things too difficult by trying to change the opinions of others to make them see their way.
