Why would you want to join an evangelical lunatic group? Wal-Mart is an equal opportunity capitalist. If this lunatic group would just sign up for the same program the gay group did, it would rake in lots of money for its cause. Instead it is steering its members to other (generally pricier) merchants, and simultaneously providing oodles of free publicity to the gay group so that IT will now make a lot more money from the program than it otherwise would have.
What is it with Wal-Mart? This excellent company seems to be a magnet for lunatics on both extremes of the socio-political spectrum.
The American Family Association may be a lot of things, but I would never call them an "evangelical lunatic group". In fact, the only folks I have ever heard refer to the AFA as "lunatic" anything is the homosexual lobby...
I think you simply have something against anything remotely evangelical (what the Bible commands all Christians to be).
