Men: Are you sexist? Why?

It is simple: ignorance. I personally believe there are inherit differences (biology and hormones proves that). In addition, some men believe these things because women are easily able to get certain things (jobs, promotions, ect.) because they cause men to think with their second head and not their most important one. Also, some men believe this because of the patriarchal idea of society and people become jealous of other people who they believe have better lives or easier lives. However, most of the people who say stuff like that have those issues.
