I have been thinking about this a lot lately. I worked for a long time in a Muslim company (fully Sharia-compliant, etc). Therefore although not a Muslim myself, I understand the requirements and the challenges of the religion, especially for 'covered' women.
Our restrooms were a haven where women would go, use the facilities, take their burkhas off, etc. The religion requires a certain amount of disrobing before using the toilet and also afterwards women would use the shared facilities to put themselves back together, adjust their headscarves, etc.
Also for prayers, women would use the facilities to do their ablutions, which also required a certain amount of disrobing.
I can't help wondering how these women, their husbands, elders, etc. are going to feel about heterosexual men with penises being allowed in these previously women-only spaces.
I also wonder how this will affect Muslim (and other religion) girls who may not be able to use changing rooms, go on residential school trips, etc. where boys may be present in these previously girls-only spaces.
And I wonder when these religious groups will become aware of how the GRA changes will affect them and if they will do anything about it.
Has anybody else been wondering the same?
