I think any person reading that thread can see by the language that you use that you are no advocate of single sex spaces.
Not only that, you seem to have little experience with the current teenaged cohort OR the fact that it seems standard that male children over the age of around 8 are either excluded directly by signage in some single sex spaces OR by known social expectations.
You also used dishonest and emotionally manipulative tactics that referred to a woman asking a polite question as ‘confronting’, ‘attacking’, ‘harassing’ and ‘abusing’ a child.
While trying to pretend that mothers with teenagers and recent teens themselves would not be able to correctly sex a teen with a high degree of accuracy.
You also seemed to ignore the very reasons that teenage males ARE subject to safeguarding processes.
Including examples like the horrific rapes in Loudon County and The Dolatowalski case.
Sorry, you can try to laugh it off and twist it however you wish. It is not that long a thread and people can read it themselves to gauge the honesty of your representations about your beliefs here and your posts recently.
