Drawing on information from four recent national and two state-level population-based surveys, the analyses suggest that there are more than 8 million adults in the US who are lesbian, gay, or bisexual, comprising 3.5% of the adult population. In total, the study suggests that approximately 9 million Americans  roughly the population of New Jersey  identify as LGBT.
Among adults who identify as lesbian, gay, or bisexual, bisexuals comprise a slight majority (1.8% compared to 1.7% who identify as lesbian or gay);

I gave you three examples. I'd also include officiating (obviously) and playing the organ from your list. I didn't try to "walk back" from anything. I tried clarifying what I meant (I had this very same problem with the word "deviates" before). I think in the Deep South *if* the "gay bakery" found it difficult to buy supplies there are more than ample legal remedies for that. Again, I'm not advocating the refusal of service wholesale, only the refusal of services which provide at least a tacit statement of approval of a particular event: what I've called (probably inappropriately) "active participation."
I'm still not taking the race-baiting question.
As concerns your American Indian question, suppose you own a bakery and they want a cake depicting Custer's slaughter at the Little Big Horn which they need for a celebration of Custer's death. Do I think you have a right to refuse to supply such a cake? Yes, I do.
I've tried to be as direct here as I could. That good enough?
