The national corporation isn’t, but many local franchisees are. There have been reports of some Wendys putting up signs that say “Eat at Chik-Fil-A today” or similar signs of support. But it’s not a corporate-wide thing and the headquarters doesn’t support it.
My local CBS affiliate did cover it. However they spent a good percentage of the report showing a still pic of the one counterprotestor at the North Charleston SC location. He was holding a rainbow flag. They reported that he said he had plenty of honks of support. Why they didn't interview him on video tape ( they could have ) is anyones guess. Maybe they did and decided he was too goofy for prime time.
Nothing wrong with a small counter protest. We frequently have them. Except if it was a lib event and one Freeper Freeping the media would go out of their way to ignore it.
