If you say that these people must use the third space then they will simply return to male spaces since their desires are not being accommodated.
I don’t know if I’m reading this incorrectly but how is this a bad thing? It’s the point surely?
Making something illegal doesn't stop something but simply means the perpetrator takes extra steps to not get caught
Yes, reducing the risk is better than getting rid of all precautions. Just because there are break ins, doesn’t mean we stop locking doors out of defeatism.
By walking into a third space I am making a public display of stating I am TS.
We are told over and over again that people (including a lot of women) don’t mind sharing loos and changing rooms. Presumably they’d be happy to use third spaces, which wouldn’t be advertised as for trans people but mixed sex. Therefore you wouldn’t be outed, you’d just be another person who was happy with mixed sex spaces.
