Proposition 8 was about one single issue, it was to amend the California constitution to ban same sex couples from the right of getting married. Nothing more, nothing less.
It had nothing to do with forcing anyone to take part in services for same sex couples. No one was going to be forced into presiding over the ceremony or be forced to allow it in their establishment, no one would be forced to teach it at school, or be forced to provide adoption services to same sex couples (by the way if you are interested in adoption and in a same sex relationship there are adoption lawyers that specialize in that already). Same sex couples had been getting married in California for months now, and the only people it effected were those in same sex relationships who wanted to get married.
This was a completely religious agenda, the prop was put together by some nut-job Mormon who was quoted on saying that it was his goal it integrate biblical law into real laws.
To me, and this may seem extreme, but its the very heavy straw on the camels back, this had destroyed any question. I used to be pessimistic agnostic, doubtful but open to the idea of a god/God(non-gender specific mind you). Call me Atheist.
