How so? When you use government to force others to service something they don't want to, you are not asking for tolerance, you are asking for acceptance and condoning.
That is not the way it works. First, you have to get enough of the population to sympathize with you in order to get such a law passed. This means you have already attained acceptance by mainstream society. Once it is passed, it becomes a societal norm. If you are breaking the law it is the automatic assumption that you are in the wrong. So people who do break the law are outside the norm and, by definition, the one who fails to be accepted by mainstream society. That's human nature.
I think the mistake you are making is the assumption that in those areas where these laws exist your position is mainstream. It isn't.
Actually in this case you don't, because you are applying law that was meant to end something entirely different, i.e. perverse and systemic racial discrimination, and have mutated it to cover any "oppressed" group out there to make their butthurt more equal than someone else's butthurt.
When laws become so trivial that breaking them becomes a matter of course, (i.e pot laws) than one has to wonder if society is really benefiting from such laws, or do such laws only benefit people who feel the need to control every little facet of other people's lives.
No. Those laws specifically include sexual orientation or they couldn't be used. Whatever you might think was the intent doesn't matter. The wording of the law is what matters, and that wording did not just pop into existence on its own.
The question put forth by the OP was whether this negatively affects mainstream acceptance and I responded no. It clearly does not. Quite the opposite.
Sexual orientation was added, mostly in places where single party rule has been the norm for decades (with the occasional RHINO). They weren't added by popular demand, they were added because the elites wanted it, and they were in power.
Just wait until more lawsuits start up, and they start going after anything related to a Church. I know people don't think it will happen, but it will.
The thing with activists is there is always the next thing. Do you really expect them to stop at the church door?
