I have several LGBT friends and family members who don’t have a problem eating at CFA. Unless I saw the local franchise owner/manager doing or saying something I didn’t condone, I don’t really have an issue with it.
Every major company out there donates money to various causes and I’m not going to agree with every one they support. United Way, the (American) Red Cross, and Salvation Army come to mind immediately, among many others. If I stopped giving my business to any company that supports one (or all) of those companies, I wouldn’t be buying anything anywhere.
To take it back to food, I wish someone other than Carl’s Jr. sold fried zucchini, and someone other than JITB sold fried jalapeno poppers. It’s annoying that those aren’t available at more fast food places.
