Decent Christians will not tolerate supremacists exploiting the gospel.
I sincerely hope so -- but so far, you're the first "decent Christian" who's even been willing to discuss this issue.
The number one issue being preached by Christians today is the gospel.
Which seems, if you don't mind me saying so, to be constantly buried in legal and political maneuvering.
Why False Religion is Worthless is discussed in Jeremiah 7. When individuals call Christians cowards for practicing their faith, they neglect to observe how Christians refrain from, through an avoidance of worldly practices, oppressing strangers and aliens.
Because Christians, and rightly so, choose not to call attention to themselves when they do so. Not that it could be any other way; "avoidance of worldly practices" is, by nature, incognito.
The issue, of course, is in those Christians who choose not to avoid worldly practices -- law, commerce, politics, etc., and choose to bring their faith into those worldly arenas... which, sadly, occasionally comes off as oppressive.
...and I'm just talking about genuine believers; never mind the cretins who will happily flock to the Christian tent because it gives them a legal excuse to be the cretins they already are.
Jeremiah 7:5-8
For if you thoroughly amend your ways and your doings, if you thoroughly execute judgement between man and his neighbor, if you do not oppress the stranger, the fatherless, and the widow, and do not shed innocent blood in this place, or walk after other gods to your hurt, then I will cause you to dwell in this place, in the land that I gave your fathers forever and ever.
Sadly, there are those who would not include the heathen, the homosexual, or (in some circles) the liberal, to name a few, in that list.
Proverbs 17:15 teaches Christians who will be affected by faithful and unfaithful practices. A Christian who refrains from decorating a cake used in a SSM celebration, honors the just and refrains from oppressing strangers.
Proverbs 17:15
He who justifies the wicked, and he who condems the just, both of them are an abomination to the LORD.
And as I have said numerous times, those who have sincere religious objections to certain business practices should not be obligated to engage in them.
In fact, as much as I disliked the Kansas bill and am glad to see it has been killed, I do appreciate one of the conditions: If an employee refuses to provide a service to a customer due to a sincere religious belief, the business owner must provide the customer with another employee to perform the service -- they can't simply shuffle them off down the road.
Not very helpful for a Mom-and-Pop shop, where the one with the religious objection most likely is the owner, but reasonable.
Christians who refrain from promoting homosexuality are not declaring LGBTs, and heterosexuals who engage in the same sexual relations, are inferior.
Those who are sincere in their beliefs, perhaps not -- but the sincere ones aren't your problem, are they?
In various social settings Christians interact with LGBTs. One major requirement Jehovah put forth for His people to practice concerns those of strangers.
Alas, some Christians are more conscientious of that than others... and there's the rub -- These allowances for religious objections only take into account the
sincerity of the religious beliefs (and how one measures that is beyond me), not their accuracy or adherence to any mainstream doctrine.
For example: Let's take homosexuality out of the equation -- the Bible condemns that; no question. Suppose, instead, the objection was to an interracial wedding. The owner could probably pull a "be not yoked with unbelievers" or something similar out of his hat as justification, and no matter how wrong he was, no matter how wrong you or any other Christian could show him to be, it wouldn't make a bit of difference, because he believed it to be true -- or at least, could convince a judge that he believed it.
...and that's an example involving a misguided but sincere believer -- imagine what a less scrupulous "Christian" could get away with? A headache for the legal system; a nightmare for "decent Christians" who don't want to be yoked to the cretins.
