To expand on Ludovic’s (and on preview I see others) answers a little more…
Californians voted in favor of Prop 8, which defined marriage as between a man and a woman in the California constitution. I’m sure people had all sorts of reasons, ranging from outright bigotry to being uneasy with same-sex marriage “being taught in schools” (whatever that means. Perhaps some saw a Gay Pride parade and the leather daddies freaked them out.
A number of estimates are a bit higher, but yeah somewhere down below 5%. There was a poll recently, however, that found that more than half of those polled thought that gays were over 20% of the population. Which is rather interesting, although I’m not sure what conclusions to draw from it.
Well, anybody can file whatever foolish lawsuit they want. But churches already have all sorts of requirements that they impose on those wishing to get married. Catholic churches, for example, won’t perform marriages if one partner is divorced (and hasn’t gotten an annulment). In states that have passed legislation to recognize same-sex marriage, the right of churches to refuse has been explicitly mentioned, and perhaps even beefed up beyond the normal right of churches to perform marriages for those they wish. California had same-sex marriage legalized by court order, so there weren’t any special protections for churches. But out of the 18,000 same-sex marriages performed before Prop 8 was enacted, I’m not aware of any that were done by clergy that were unwilling.
There was the case in New Jersey regarding a church owned pavilion that the church denied the use of to a same-sex couple and was successfully sued. That case revolved around whether the pavilion, which was often rented out to the public for a variety of activities, was a public accommodation. And there was a case of a wedding photographer in New Mexico who refused to shoot a same-sex wedding. I have no idea why anyone would want their wedding shot by a photographer who doesn’t want to do it, but I guess someone did, and they won the case.
A few states have made non-discrimination a requirement to receive state money. Massachusetts has gone as far as to require non-discrimination in order to be licensed to provide adoption services. Catholic Charities in the state decided to follow the law, but was overruled by the Archbishop. They no longer provide adoption services in Massachusetts.
Various states have laws granting or forbidding medical providers from exercising their religious views at work. I’ve never heard of a case involving in vitro fertilization, though.
Families have had trouble with religious intolerance of homosexuality before. Most gay people aren’t anti-religion. Also, homosexuality isn’t a way of life. And children raised by same-sex couples are straight. I think I’ve seen some figures showing that they are very slightly more likely to be gay than children raised by opposite-sex couples. Probably just being more willing to be honest about it.
It doesn’t really matter what the child wants. Their sexual orientation isn’t a choice. Children of gay couples If they are gay, and the same gender as the parent then they ought to be able to get relevant advice. Otherwise, well, sex education seems to be pretty much mandatory. And there are other people in the world that can answer these questions.
This doesn’t make any sense. As far as I can tell, this last part is mistaken in so many ways that I can’t figure out how to explain where you went wrong. Your scenario seems to require that straight people stop having kids. I don’t know why you would think that.
