Do you think it is reasonable to equate a hate group with two innocent people just wanting a cake for their wedding?
It may be reasonable to dislike KKK members. But there is no reason to dislike innocent people that just want to get married.
Steady on old chap, comparing and contrasting does not necessarily imply equating. I have tried a few scenarios, that one, at first glance, seems easier, which is partly why I tried it.
So, could I take it that you think I should have to make a bun with KKK on the top, or not?
If the latter, you might justify it by saying something along the lines of what you just said.
If the former, the the KKK customer might challenge me by saying his organisation is legal (I am assuming it is legal?) so what are my legal grounds to refuse?
We are assuming that I put text on buns for other customers.
Perhaps discriminating on grounds of thinking an organisation immoral is not an anti-discrimination law? I don't know. Perhaps groups like the KKK are not protected in the same way that other groups are.
In any case, after you've answered, try this one. I think it's less clear cut:
I am a strongly pro-choice banner-maker and I am asked to make a banner for an anti-abortion rally. Should I be obliged, by law, to make the banner (all other things being equal)?
I don't know the answer myself, so please don't think I'm trying to win a point.
