a) equally hard, given the common understanding of what “facts” mean nowadays, or
b) nudity is harder, given cultural contexts.
Culture makes a lot of difference for what’s considered nudity (e.g. women breastfeeding goats, as illustrated in the link), and it should matter less for statements about average temperatures for a given region, etc. But the “facts” as presented are contested anyway, since they are derivations based on data + interpretation, even if the interpretation is from >95% of scientists in the relative field.
That makes me lean more towards (a) even though I wish it was (b).
I think we still have a misunderstanding. I am saying that enforceable rules for nipples are easier to write, regardless of the cultural approval of those rules. A well written rule can be enforced by only looking at the content that is on the platform ( eg the image). That is not to say people might disagree (its Art!) or they might get it wrong (its a male nipple).
When it comes to statements of fact, this is not the case. The enforcers must draw conclusion based on off platform research, a presumed intent of the post, and/or a presumed interpretation.
In which case I’d have to agree! Thanks for taking the time to clarify it for me.
