It certainly has its niche. For instance, things like bras and tampons are very much useful only to one gender. Obviously it's applied to products that really have no reason to be gendered, but that doesn't mean it's inherently sexist, just that many (possibly the majority) of its current applications are sexist.
Fair enough and well said (although transgender people and such need tampons but w/e,
mostly only cis women need tampons). I was more referring to the whole bullshit with Bronuts and Dude Milk and gendered soaps and shit that doesn't NEED to be gendered.
Acknowledging differences between genders isn't sexist. Now, one could argue (with legitimate grounds) that some gender differences are social constructs, but others are basic biology. For example, men tend to be better in abstract thought, whereas women are usually better at distinguishing minor details.
The sample sizes in those kinds of studies are usually laughably small, and therefore aren't actually reliable in measuring the capabilities of men and women (groups that include BILLIONS of people) in any form, shape or size. It's simply inaccurate and reductionist to say that "men are naturally better at thing X" or "women are naturally better at thing Y".
Of course there's differences in brain types, but since physical sex is a spectrum rather than a strict binary anyway (as evidenced by the existence of intersex people and chromosome/hormone variables within individuals) and sex =/= gender, that's a WHOLE different discourse.
(and shit like distinguishing minor details and abstract thought usually has fuck all to do with marketing anyway :| )
