That does sound like what it means.
The behavior of the "tech bro" in question is certainly offensive and insensitive, however using terms that bigoted in a headline (shaming a minority group in "tech" for holding different political views) is something one would expect websites on both extremes of the political spectrum to engage in (Vox, Breitbart, ...) rather than the Washington Post, and it's a bit sad to see them resort to such outrageousness.
It's also disappointing to see HN moderators be OK with headlines like this.
