Sounds like a positive step to me. Catholics and other religious groups who share similar prejudices should follow the example.
Would be great to hear Mass celebrated bu a woman.
The Islamic faith is not really approving this and they don't have the structure of the catholic church etc. You can be Christian and get married, just not in the catholic church and a few others. Try finding an Islamic country or imam that will marry two men. In most you would be lucky to just not be killed. India just re affirmed that gay sex is illegal, lets blame the catholics for that and in many middle eastern countries they are put to death, must be the catholics fault again. Don't like catholics, don't become one or if you are become something else. That is called freedom of religion. You don't like what they believe, good on you but unless what they believe is forced on you, you have no complaint. Jehovahs don't like blood transfusians, well unless the government decides to ban such because they don't like it, I don't care. Unless Harper plans on putting new laws in outlawing gay marriage I don't care if catholics don't like gay marriage or muslims etc.
