The bigotry of that era was government mandated, from the State to the Local level. It is not the same as a single or few vendors for a ceremony they do not approve of asking the people to go to someone else. And some vendors only specialize in certain weddings, be it Jewish, Catholic, Black, or anything else. The main issue is there isn't a group of butthurt protected class advocates gunning for them and trying to ruin them. Most black people prefer to use vendors that cater to black culture, and there are other examples with other ethnic groups.
Again, where is the harm? Where is the systemic economic harm (and its corresponding political harm) that these laws were designed to fight in the first place?
In my Christian faith (Presbyterian), the minister has never admonished the congregation to avoid commerce with homosexuals. Avoiding such commerce is not a basic tenet of Christianity. It is, rather, dogma derived from an obscure piece of scripture. Christ Himself never admonished His followers to avoid and decline commerce with anyone. So, a few bigoted folks are using Scripture, twisting it to serve a bad purpose.
And now these bigots want legal protection for their bigotry. Pretty much the same as mandated bigotry.
If these bigots can pervert a loving, forgiving and beautiful faith to serve a vile purpose in one instance, what prevents them from turning their bigotry toward other Americans.
And you said people are 'gunning' for these bigoted merchants. How? By coming into their places of business as paying customers expecting the same high level of service each and every other customer expects? Only to be humiliated and turned away because they do not fit cleanly into the cubby hole some narrow minded bigot demands?
Should. we have second class citizens of this nation? Should a few bigots call the tune? Where was their Scriptural mandate before?
