Opting out isn’t an option, even for Aboriginals who have special rights. Aside from what appears to be punitive religous applications of civil society, its laws, like not wearing a mask; gender can also be used for civil society measures in, for example, community colleges. In Ontario, as a practicing example, female only classes at George Brown College bar males and any person identifying as a female in any way without all female physical traits. It may not be the practical application of civil society and its laws, but a punitive act based in them. The mask may be removed, but application may require special exception once it is; see timeline on this issue.
It may be necessary, especially since the political parties (e.g. NDP) signed the AFN – INM treaty, for the AFN and Aboriginals to ‘opt out.’ Education, especially post secondary and bridging programs, make Aboriginals vulnerable when this is not necessary.
