Everyone knows that you don& #39;t teach relativity or quantum mechanics in primary school. Similarly, "XX => female" and "XY => male" is fine up until college or university - but it& #39;s only a generalisation /10

The exceptions are only relevant when talking about trans or intersex people, just as relativity is only relevant on the cosmic scale.

People don& #39;t need psychiatric help with relativity. So why should they need it if they find their sex is different from their genetics. /11

Intersex people exist. Trans people exist. They are unusual, so trying to apply the usual approximations is like applying Newton& #39;s laws to things moving near the speed of light. Legislating such things is as insane as legally ruling that Pi=3 (which also happened) 12/12
