Feminism points out, though, that the social mainstream is also a strong political identity which systematically distorts people's maps.

This sounds awfully like "if you're not with me, you're my enemy." Any advice how to untangle myself from this web that seems inescapable? I already don't vote or read the news from any particular source, nor do I actively try to change political opinions.

People with agendas seem to want to make everything about politics and me as their pawn as a consequence. When they try to take my passiveness IRL as a sign of opposition to their political agenda, I usually proceed to explain how much more of a political enemy I could be just to demonstrate my point if I cared to.
