Sorry you had to put up with this, and I applaud your courage in telling them exactly why you were taking your business elsewhere.

I say it that way because some years ago, I was collecting bids for some work on our house (I think it was having the roof done, something routine). When I realized that one of the companies involved was using their Christian identity as a selling point (which was horribly common in that period), I called and told them I wouldn't be using their services. Sadly, I was too afraid of the possibility of harassment, that I wasn't explicit why. I hope that now, I could follow your example instead.
