Absolutely. You're right that freedom of religion is a great value. I don't buy that Odin is a god you believe in, anyway.
Either way, I'm just pointing out that the nature of the claims is different - the claim to be Almighty God is very different from the claim to be one god among many, just by nature of the claim. But I know it's just a joke meme poking fun at Christians, so it's not really that big of a deal.
