Why are women so difficult to get along with?

It doesn't matter if you are dating them or working with them they always seem to have a problem one way or another with something you are doing. I had a girl the other day complain that I was eating my candy bar with my hands. The criticisms are always asinine and serve no propose of advancing ones social skills. If anything the only thing women have done in my life, are cause me to revert socially into a person who is becoming more social inept everyday. There is no positive feedback when dealing with women. You tell them your name and they instantly think you are a weirdo. I don't understand how eating a candy bar with my hands makes me a caveman. I get made fun of for working a full time job. Scoffed at for taking extreme measures after my last family member died to save money so that I may survive. I never get treated like this by men, only women. Why are woman so hard to deal with?
