As one who had run their own creative agency for 10 years, I had to take a look at Smith's "site" and agree with your assessment. Love all the quotes from "people" who are simply thrilled with the high levels of professionalism and service over the years. (The quotes that are attributed to people like "John" and "Sandy" with no last name, company or even indication of what services were provided - lol)
Over the years, there were several companies we refused to do business with - you know what though? We didn't openly discriminate based on our shallow "beliefs" - a very simple "I don't think we're the right firm to handle your project" and an estimate given at 3x our normal rate always sufficed.
Oh, and if Smith wants to use the Bible to defend her bigotry and intolerance, might want to read Leviticus 19:28 which has something to say about those tattoos she so proudly displays on her site...
