This is exactly why every month or so when I check out Facebook to see what's going on I don't respond to things I see like I would here, no matter how much I might want to for a bit. Even if a similar topic comes up on FB and I've just posted a large comment here with multiple sources against a point of view, on FB at most I'd probably post "Eh, I'm not sure that's quite right, at least according to this. <link>". Almost nobody there is actually interested in having their point of view challenged or learning more about the thing they're posting, from my experience, so that's about all you can do in many situations without things just devolving or people ignoring you.
