I have seen a number of pieces claiming that there are no biological differences between men and women that would lead to men having a clear cut advantage in athletic competitions.
I remember reading something like that in The Atlantic which was roundly criticized because it was stupid. August thought The Atlantic may be, I don't consider it a scientific publication; what articles are you referring to?
There are many people in my life (that I care about and respect) who believe in young earth creationism; I do not believe it’s actually a fringe belief in the US.
That said, I do not believe they would do well in a science/academic role because it shows a clear disregard for many separate academic disciplines at this point. And these religious views are not evenly distributed across the political spectrum.
I think one would be hard-pressed to find anyone who claims there are no significant differences (at some point, the question reduces to one of definition).
The argument is over what those differences are, how much they matter (i.e. a 1% difference in the mean? Who cares), and how malleable they are given modern medical science.
(And that's before one gets on the topic of whether those differences should imply a societal structure that pigeon-holes people based on their biological sex).
I’ve never met anyone who has said this, and I’ve worked in quite left wing spaces for a long time. I believe you may have fallen for some caricature or other of the left. I’ve no doubt someone has said that, but I think you’d find that belief in bigfoot or flat earth is more common, because it’s quite apparent to most that there are indeed differences between sexes. I think what tends to trip people up are what I call “dude looks like a lady” situations where people, either through accident of birth or other means, appear androgynous; it seems gender is more of a bimodal distribution rather than a strict binary. Again, this seems rather apparent to me just having met some people who don’t exactly fit the mold, but apparently this is also something of a political controversy.
