It is a Christian institution though, it's not like his ideals have come out of the blue, your not just affirming equality your overturning thousands of years of belief and upsetting a certain demographic , I see no reason to upset religious sensibilities when a perfectly good compromise is on the table, all this does is lead to the banning of both civil union and marriage between same sex partners as the argument inflames both sides and contention turns against even rational concencus; in a mainly religous area, your unlikely to gain support if you don't give a little to get a little. You don't have to agree with the ins and outs, but if the two sides get something they can agree on it will smoothe relations?
