This case does not establish any law prohibiting the quotation of Romans 1:21-32, Leviticus 18:22, Leviticus 20:13, and 1 Corinthians 6:1-10.
Besides, if a professional anti-Semite like Ernst Zündel can't be convicted under the Criminal Code for inciting hatred, I doubt that Owens can be for making references to a few Bible verses.
It doesn't establish any law. It does however, establish something else quite important in legal matters. Precedent.
Yes, you may quote the above verses. However, you'd be well advised to think carefully before doing so, lest you find yourself entangled in litigation with this case as precedent.
Thus, the effect may not be disimilar to the outlawing of these verses.
I'm glad I live in a country with freedom of speech and freedom of religion. In your country, a man may not publicly quote the Bible. Whoa! You live in a liberal humanist theocracy.
