I not only got out of it, I killed your argument but you aren't smart enough or honest enough to understand it.
You didn't address the difference between providing a cake and providing a cab ride. You just said it was too dumb to discuss. A cheap way out, IMO, hence my appraisal of why you lost the argument.
Ok, I see the problem, you jumped in on a discussion and I mistook one left wing nut for another. Let me make it as simple as I can:
Providing a pizza or a cake, or a cab ride to a customer, is not the same as actively getting involved in a ceremony or activity. The key word is "actively". Walk in, order cake, leave with cake, no problem. Walk in, order cake with two plastic men or women on top, demand that it be delivered, problem. Demand that a photographer coordinate the wedding photos, problem.
There is a huge difference and though it may be discrimination, Americans should have their right to practice their faith trump the non-existent right not to be discriminated against.
Clear?
