Forced to do what?
How does baking a cake violate the tenets of any religion?
And will these oh so holy people apply this refusal to all people who sin or just some people who sin?
IDGAF if people refuse to serve someone I just want them to be honest and consistent.
The problem contained in your question is that religions aren't 'official' or based on specific identiable sets of beliefs.
Your religion, essentially, is whatever you want to call your religion.
Not entirely. Usually there has to be some consistent tenets etc.
and the oh so holy people can't pick and choose the tenets they follow right?
Surely if baking a cake for a gay person is a sin then baking one for an adulterer is a sin, a thief? a murderer?
Seems to me with all the sinners that baker sells to his soul is already damned to hell so why not make a little money on a gay wedding cake
