I was mostly assuming right-leaning people in the US tend to be Christians, pointing out that a cohort known for projecting their problems perhaps isn’t the best to contrast with.
My comment was somewhat flippant, but you raise a good point in that not all Christian denominations maintain a persecution complex. A generalization on my part, I admit.
It occurs to me now that I don’t quite understand your point. Are you suggesting that people tend to accuse groups they don’t belong to of a “grievance-based identity” as a strawman? Or is your point about drawing a parallel between accusatory conservatives and concerned mothers? Or is your point perhaps simply that the author is othering her child?
