This case was never about refusing service to LGBT couples, it was about refusing bespoke work. To paint it as anything else, and in defense of your argument that "Conservatives are anti-LGBT" because of this case is wrong and nothing short of propaganda.
White supremacy is on a lower tier of protection in America than things like race and sexual orientation.
Your argument that the baker was merely refusing to serve the customer because of the "content" does not hold up.
