If it is a commission I for sure can.
I am not obliged to work for you if I do not want to.
And I am not going to tell someone why I do not want to accept a commission. That is my own business. Maybe I find your whistle breathing annoying. Maybe you remind me of the bimbo who used to tease me in high school ago. Maybe I do not approve of your boinking every thing you can get to hold still. Or maybe I do not have the time.
It is none of your business why, all you need to know is I either accept or do not accept.
People get themselves in a lot of trouble by trying to get other people to agree with them. So they spend a lot of time explaining. I don't.
?be assured I I was not all referring to being obliged to work or do anything for me - and certainly do not think you should be obliged to accept any request - for in context this is about the Masterpiece case and I was explaining the events that took place and the legal reasoning at work here, and how that could apply to you.
In which, not knowing much about your business, you would have to explain the difference btwn Masterpiece not being able to legally deny being commissioned to create a special work for the expressed purpose of celebrating a homosexual union, versus if your business was requested to do the same.
