I just read the article and it does say ‘women and their petiods’ many times and only once says “asked 548 menstruators”
I didn’t actually read that as being women erasing necessarily, more that they wanted women who currently menstruated to answer the specific question about how it affected work in recent time.
It could have been worded ‘women who menstruate’ but because the rest of the article had no attempt to erase women, I’m not so sure this is a clear case of trans politics at large
