Donate through another source. Just not them. But contact them and voice your displeasure. Hopefully we get a list of NBC sponsors that can be contacted as well. Nothing short of a full retraction, apology, will be accepted. Get ready to not watch their programming because I think the retraction will not be forthcoming.
But contact them by email. There is no reason to be tying up phone lines with complaints when others may want to be calling in donations.
Remmeber getting money into the area to support those in need right now is the most important thing.
The only NBC show I really watch anymore is ER, but that turned into the latest Bash Bush, Bash Christians trype that I would be glad to tell them why I stopped watching their network.
