I'm a biologist and I teach biology. Part of my job is to teach them what boys and girls are, and what the words male and female mean. WHAT SHOULD I TEACH THEM, RSB? WHAT WORDS SHOULD I USE? https://twitter.com/RoyalSocBio/status/1314556133051375618

In addition to teaching the legacy 'facts' of science, I also teach what science IS and how it WORKS.

Is being male or female a matter for subjective determination by the individual? Is this part of science now? Does it extend to other animals, and if not, why not?

TELL US, RSB. ENQUIRING MINDS WANT TO KNOW.

This is YOUR problem. YOU are custodians of the legacy of natural scientists who have painstakingly sifted what is reproducible from all the error and bullshit and wishful thinking.

#IAmABiologist and I have no use for a @RoyalSocBio that can't define sex clearly enough to allow children to be taught their own biology. And I have no use for a @RoyalSocBio that has more interest in political band-wagon-jumping than science.

[I edited this tweet while I was composing it and made it say 'them' instead of 'children'. For the avoidance of doubt, I teach children. Often I am called upon to teach them what sex is, and often while they are going through puberty. The obfuscation I am asked to indulge in...

...on this subject, at this stage of kids' lives, is inhumane and a massive failure of science and science education.]
