This is where I honestly feel for the mods. On one hand, sensitive stories involving people belonging to historically disenfranchised groups require a watchful eye when people try to squirt their shitty little dog-whistles and winks into their posts without giving away their true intentions (the "I'm just sayin'" or "Just asking questions" shit).
On the other hand, stories that have major inconsistencies or problems should be open to discussion, IMO.
But when those two topics intersect, what can you do? If it's too open, racists and homophobes (as rare as we may like to believe they are on this website) will post their thinly-disguised horseshit with aplomb because they know they can just fall back on saying they're "playing airchair detective" like everyone else. But if it's too closed down, it's a circle-jerk where anybody who dares give an opinion that doesn't line up exactly with the majority gets shouted down, insulted, or possibly banned.
Play it safe or leave it open.
Damned if you do, damned if you don't.
