Humans are a bunch of individuals though with an incredible amount of diversity. If their claim is biological, it would be helpful to pin down more precisely what they mean, because right now it's pretty vague. I'm dubious that there's a rigorous claim here though because pretty much every time I've seen a claim like this before it's essentially just protection of one's personal beliefs about psychology without more of a basis than assumption that their personal experience is universal, which is what the comment you're responding to is alluding to.
