I think that this sounds like an HR issue. I had to make a sexual harassment complaint against a male co worker. That ended things. Also, I posted a large printout of the definition of the word "stupidity" in my work area. The definition I used was "stupid - unintelligent: lacking intelligence; "a dull job with lazy and unintelligent co-workers." Along with this definition of the word Ignorant : "ignorance - the lack of knowledge or education." I then concluded at the end of my printed out decoration with "Ignorant people simply don't know, while stupid people refuse to learn. Ignorance is understandable- stupidity is pathetic." That seemed to help a bit.
