Typical but by no means exclusive of right-wingers, this variant of "whataboutery" is the final cop-out used by those too blinkered by ideology, bigotry or religious zealotry to concede that their argument is all over the place.
Look at the way, for instance, it's often deployed by closet homophobes.
When the subject of sexual equality for all is raised and facts are spelt out about past or existing discrimination, the latent homophobe will not say something appalling in return, but will instead cling on to the lame "yeah but, anyway, not everyone is obsessed with gay rights" as their pathetic last resort.
"Not everyone is obsessed with..." can be perused whenever truths are starting to grate or when arguments have run dry over whichever subject doesn't suit your warped ideological worldview.
Low wages, inequality, the environment, human rights, misogyny, cruelty to animals, balooning transport fares, the cost of education, you name it. Not everyone is obsessed with 'it', no matter how wrong 'it' is, which might as well read "let's leave things as they are, because I actually quite agree with 'it', even though I haven't got the cojones to openly say so".
Of course, you'll find the people coming up with the above remark will probably not grasp the irony of them being obsessed with issues as vital as supporting angling or the abolition of speed limits.
