It can be. "Sexual harassment" is kind of a broad term that could include just about anything.
this is a dismissing tactic to imply that sexual harassment is some sort of pseudo law that isn't fair, with often the implication that it's a giant conspiracy to allow women and evil feminists to screw over men.
sexual harassment is a crime. it's a real crime. tech has a sexism problem.

Note this quote: "The conduct of the harasser must either be severe or it must be pervasive to be sexual harassment. A single incident is probably not sexual harassment unless it is severe. For example, a single incident of rape or attempted rape would probably be sexual harassment (it would also violate criminal laws)."
