@Chersfrozenface you say “But you can't base laws and policies on beliefs that are contrary to reality.” Then you go on to say
“Even if a male person believes he is female or non-binary, he is not and never will be. That fact has to be acknowledged in law and policy. The same with a female person and her belief. The same with any individual and their "trans identity" beliefs.”
The GRA and EA2010 are laws based on GI belief and conflate sex and Gender Identity Belief. Repealing the GRA is not going to happen, amending it to be based on GI belief and completely separating it from sex is the most likely outcome. This means sex reverts in law to human male or female and not the ludicrous legal sex version we now have.
People who believe in God have protection under the religion and belief pc. Those who don’t believe in God are similarly protected. GC belief is protected so it is not unreasonable to have the GI belief protected as a distinct belief. This is totally separate to sex.
There is eventually going to be a huge bun fight over definitions as I very much doubt there is a clear and unified definitions of trans, gender, non-binary etc. Sex is much easier as sex = human male/female.
