I'm not sure why an opinion being commonly held across race/class/gender would make it not political.

Your statement that the immigrants you know care about x and y and not politics doesn't actually make sense in response to the concept 'everything is political'. You are responding from the perspective that politics means elections, or some similarly narrow set of topics. But 'everything is political' explicitly rejects that perspective. It means that a Filipino immigrant thinking about whether their uncle and cousins will be able to visit them is political because it's harder for them to get a visa than my English cousins. It means that a Hispanic immigrant talking to her friend in a restaurant after dropping the kids at school should not risk being detained by ICE because speaking Spanish makes some dropkick immigration officer decide they must be illegal immigrants, which happened in Montana.
