In the eye of the "Beholder"

It is hard for me to "understand" why an artist would
berate a form of art.....be it, mixed media, decorative painting, fine art, abstract, photography, sculpture, etc.

I can almost always find one or more positive aspects  in someones' artistic license.  The texture, color, design, etc.   Even if I don't like it .... which is rare.. I respect it for what it has meant to the artist and I would never berate the artists' work....  Even something one doesn't like can be a positive help in their own art.
