It's hilarious. Even if a TW did have a uterus (presumably in a shoebox under their bed) they wouldn't have the fluctuating hormones that cause periods and the associated symptoms.
And for all those saying that it's not fair to hold up one nutcase and pretend they represent the group, the problem is that the rest of the group is going along with this nonsense. It's frankly only half a step further from "some women have a penis, some men have a uterus, biology is a social contruct" anyway.
What's even more funny (or sad, depending on how you look at it) is that I've suffered from those 'validating' symptoms of menstruation for years and only now (as a 30 year old) am I starting to understand that a lot of the 'symptoms' are caused by interpreting womens bodies through a patriarchal lens.
Migraines and painful cramping? - Related to my hormonal birth control, which i never truly needed and will never take again (natural methods are MUCH more accurate than we were told in sex ed. We were basically told not to bother, turns out they are more effective than hormones when done correctly).
Chocolate cravings? - Magnesium deficiency. You're not gluttonous you need a mineral that is lacking from our modern diets and men don't suffer from the lack of it but it's crucial for women especially at this time. Cravings are there to inform you, take a supplement.
Hungry constantly? - While men can eat the same amount every day, womens intake needs fluctuate through the month. You're starving and binging when you're bleeding because you actually needed to gradually increase food intake in the week BEFORE you bleed, but you ignore your body's requests because you've been told you should use self control and eat the same amount all the time. If you pay attention theres a reverse around ovulation where you can comfortably eat much less than normal so even if youre trying to control your weight you can do it while moving with your body's natural rhythms.
Tired? - women's bodies have fluctuating energy levels as well as food. You're supposed to rest more at this time. Again, it swings back at ovulation when you have more energy and need less sleep.
(all of this is backed by science, not just my personal experience)
Sleep in, eat more, take some magnesium, and do yoga instead of cardio, and my period becomes a quite relaxing, rejuvenating time instead of a monthly torture.
