Why Is It "Bad"?

Ralph Pugay, Liondix, Acrylic on panel, 12" x 16", 2010. www.ralphpugay.com

Why do we feel the need to call our paintings "bad", "naive", "hobbyist", "crafty"?  
Why can't we just let them be what they are going to be?  
Is it because we are insecure?  
Is it because we want to make sure everyone knows that we are self-aware?  
Does it legitimize the paintings?  
Does it make the paintings humble?  
Does it make the paintings pretentious?
When we make a humorous painting, is it automatically sorted into one of the categories in my first question?
Who does this sorting?
Why are we uncomfortable laughing at a painting?
Is it because it lowers the entire art form?
Is this a bad thing?
Is painting not supposed to make us feel those emotions?
Does a painting have to be witty or conceptually intriguing if it is also "bad"?
Can a strong concept make up for poor aesthetic choices?
Who is evaluating this balancing act?
Must we always tip the scale one way or the other?
What is the difference between painting and illustration?
Is an illustrative aesthetic "bad"?
Why do we have to put "bad" in quotation marks?
When will irony die?
