I disagree that American-right leaning people are anti foss. rather FOSS is great because it has zero political inclinations. Rather, as some who interacts with all sorts of people across the political spectrum, in fact most of my friends who are American-Right leaning or republicans, are the ones pushing hard for foss software, my American-left leaning friends are more generally neutral.

Rather, I think that in general, the more politically inclined someone is, regardless of political stance, the easier it is to convince them to be pro foss.
