Is this legal?

I'm making a book about a little adopted boy with two dads. Today, I got a call from a publishing company that I have been with for over a year. I dropped my older book projects, due to time stress and made this one (a childrens' book). Anyway, I told the guy what it was about and he started talking about God and said that it was a Christian organisation. I had no idea. Then, he referred me to another company and said in this condescending tone "God bless" and hung up. Is this legal? I thought we could publish anything.
