was that a drawing of the presenter? or just following the statistical prevalence of male programmers? was his male-ness really the focus of the picture, or was the artist just using the proper pronouns for the character? was his masculinity being presented as the cause for his behavior?
It does suck that a man is the default for this, but IMO it's a projection of toxic masculinity (i.e. Patriarchy).
IMHO domestic violence has complex roots and it wouldn't be beneficial to try and draw any conclusions by finding correlations with one variable.
