Funny they would say it's racist...
The gov of Canada allows any of its employees who identifies as first Nation to take extra days off to participate in traditional practices (including fishing and hunting), which is something that doesn't exist for anyone else and to me that's discrimination towards anyone that isn't Christian or first Nation considering our holidays are based on Christian celebrations...
Edit: Guess I wasn't clear? Our holiday calendar being based on Christian celebrations and first Nations getting a guaranteed 5 days off to celebrate their traditions is discrimination against people that aren't part of either group since they're at the mercy of their manager when it comes to being able to have a day off for their traditions/holidays.
