The societies for the study of evolution (SSE), the American Naturalist Society (ANS) and the Society for Systematic Biology (SSB), issued a joint declaration addressed to president Trump and members of congress with a confusing definition of sex, implying that sex is not binary.
We wrote a short letter explaining that sex is indeed defined by gamete type: https://whyevolutionistrue.com/2025/02/19/our-letter-to-the-three-societies-on-the-definition-of-sex-with-signers/
We are now collecting more signatures from biologists that agree to have their name publicly posted. If you are a biologist (or in a field related to biology) want to add your name, just fill up this form (it contains the full text of our letter and a link to the tri-societies' letter): https://forms.gle/3i2wv3BUaZYDB3Fe9
Both Jerry Coyne and Richard Dawkins have written posts about this:

Please forward to others who might be interested.
This is a very important action -- and I hope many more biologists will add their signatures to the letter. Scientists need to stand up against ideology and pseudoscience!
I'm not in higher ed, but even we in K-12 science education need to help hold the line against ideology and pseudoscience. So, I added my name to the campaign!
