That appears to be happening, at least in this (southern VA) area. Chik-Fil-As seem to be packed all the time. The homoerotic community should by now be finding out boycotts don't work. One group of people call for a boycott, then opposing groups give additional business.
This may work out to be a "Thank You Jesse Jackson" moment (you Chicago folks knowwhatimean?).
I remember using the BuyBlue.com website for that purpose. It would list all the top donors to conservative causes and I'd go out of my way to patronize them more often.
