But the problem is, that wouldn't even come close to destroying their business.
(I found the best numbers I could.)
Ok, so there were 10,000 gay couples who get married 2014 (in the entire US)
Now let's say there are only 50 bakeries (somehow) in the whole of america
That's 200 couples / bakery
now on the other hand we have the 2,189,000 breeder weddings
again there are only 50 bakeries
that's 43,780 couples / bakery
if all the gay couples chose not to buy cakes at those bakeries, they'd lose around 0.5% of their business
unless the bakery is doing VERY poorly already, that wouldn't take their entire business down
