but if you're not committing the gay sin how is baking a cake for someone who is gay a sin?
None. Of. Your. Business.
Maybe you should write this down, because you absolutely SUCK at remembering to quit being a nosy, controlling busybody.
Still not an answer to what is a very simple question
And it happens to be a relevant question because that is the argument used by the bakers as a reason why they refuse to serve gay sinners but will serve any other sinners willing to pay for their wares.
Why is the gay sin so much worse than all the other sins committed by their customers?
No, and it's not GOING to be an answer to your question, because you're not entitled to one. It's NONE OF YOUR BUSINESS. "What color panties are you wearing?" is also a simple question, but I wouldn't answer THAT, either, because it's personal and it assumes that it is okay for you to ask things that are NONE OF YOUR BUSINESS.
Speaking of simple things, why can't YOU understand a simple concept like minding your own business?
If the baker wants to engage in this conversation, then feel free to go ask him. THIS particular debate, however, is with ME, and MY position is that the First Amendment guarantees me the right to exercise my religious beliefs without any need whatsoever to explain, justify, or ask approval for them.
Decide who you want to talk to, and make it so.
