If I want to sing my nations anthem I do.
Is this a secular nation or not?
Canada upholds many historical trappings that do not reflect what the nation is moving forward.
The long and short of it is, the laws you live by should not be decided by religion. That's a very crucial, meaningful, thing. Your obsession with one word in a historic anthem, trivializes what religious freedom actually means. You're confusing religious expunging, with freedom. The two are not the same.
