Gays (lesbians, in particular) are all over the bakery industry - just look at the Food Network or an episode of The Barefoot Contessa or Chopped. A conservative could go into one of these bakeries (try NYC!) and request some anti-gay cake message on their red velvet. But conservatives are not good at organizing and are usually at work, so it never gets done.
I am in MA. I would do it if I could find a confirmed Liberal bakery. But I’m not prepared to spend a lot of dough going from business to business to weed one out.
And yes....pun intended.
