Since Canada has freedom of religion, what's stopping someone from claiming that they belong to multiple religions to simply claim the bennifits of those religions?

If you claim that you are Muslim, you can discuss Islam however you want without being called an islamaphobe, or dislike gays without being a homophobe. You can check out young girls and claim that it's your culture.

If you become Sikh, you don't need a helmet when riding a motorcycle and you can carry a cool dagger.

Can you have more than one religion?
