In mid April, the news came out that Nike was sponsoring studies aiming to analyze the effects of things like puberty blockers on children and teens with gender dysphoria--more or less seeking to answer questions about whether it is fair for "trans women" (i.e. men, XY) to compete as women at various levels in sport. So far, Nike has not answered questions about the study, and in my mind, what this does is to assure me that yes, Nike did initially sponsor the study, and they're either hoping that the storm blows over, or they're considering truncating or ending the sponsorship.
(Thankfully, they do not appear to have provided enough money to actually fund the transition procedures, so the subjects of the study victims of the new Dr. Mengele will need to find other sources. This should at least cut down on sample sizes and statistical power.)
Well, in that light, I encourage my "legion of readers" (ha) to help Nike to see that it is unethical to do experiments on children with permanent side effects. How so? Well, if you're buying Nike shoes and apparel--and this would include not just Nike, but also Converse, Cole Haan, Bauer, and Jordan--just stop, and send Nike a nice note explaining why. Then, you can go further, and stop wearing Nike shoes and apparel.
Yes, if you have a lot of Nike shoes and apparel--I have precisely one pair of Nike shorts in my wardrobe, so it's easier for me--it means a certain amount of adjustment, but the consequence of not doing so is that young people will be hurt, and Nike will continue to think they have carte blanche to do this sort of thing.
