Look, I grew up catholic and I'm a massive nerd, and even I think expecting the laity to know or care about theology is a bit much.

That being said, these supposed catholics don't even care about doctrine or obedience, which is, like, basic catholic shit. They're all heretics wanting to do protestant stuff (personal relationship with God, salvation by faith alone, etc.) and to call themselves catholic. If the church wasn't so washed they'd be excommunicated or worse by now.

They should all do the cool thing and just renounce the church altogether. "So, because you are lukewarm and neither cold nor hot, I will spew you out of My mouth!" and so on.
