The cry of the gay lobby was always that "we're not out to make you do something you don't want to do".
Well now, it appears that the gay lobby is doing just that. You will photograph my wedding, or you will pay the consequences.
I think most of the LGBT still holds to the
"we're not out to make you do something you don't want to do" philosophy, just like most atheists are not militant atheists, and most Muslims are not terrorists, and most Christians are not homophobic bigots. It's a shame that the radical elements in each group get so much publicity and end up controlling so much of the population, rather than allowing the rational non-extremist majority to rule....
I was going to respond in detail, but I think I can encapsulate to the "points" you brought up.
First, we're talking about boundaries;
Second, we're talking about privacy;
Thirdly, we're talking about rules in place (such as gun control) that are there to make the world a safer place; and two gay people using the goods you sell them to facilitate a gay wedding doesn't place anyone in harm's way.
The truth is in the middle somewhere - what one person considers harmful, another person does not, etc. etc. If someone's conscience dictates that a certain action would contribute to harming another individual, let them follow the dictates of their own conscience.
There are laws against monopolies - there will always be more than one bakery, more than one photographer, more than one flower shop, more than one building to get married in etc. etc. Why would anyone go out of their way to target a business which does not specialize in a particular set of services, instead of supporting the other organizations that would gladly cater to what is needed?
To the fanatics, it's not about the wedding cake/flowers/pictures etc. ... it appears to be a matter of hunting down those with different beliefs, and trying to force business owners to go against the dictates of their own conscience.
