No. Phelps and his crew have been at this for decades, and were spouting hatred against homosexuals long before they got into the national spotlight by picketing funerals. They are very sincere in their complete hatred of homosexuality.
Hatred is a funny thing though. Makes people rather easy to manipulate. Allows people to justify a lot of things including very strange ‘bed’ fellows. Could still have a funding and influence from a sophisticated wealthy source.
