If you’re really interested in “standing with Laura” (and I’m not; I haven’t watched Fox News in a long time), then the most effective way to do it is to boycott the OTHER hosts on Fox News.
That hurts her too, because most of her advertisers aren’t specifically targeting her show to advertise on. It’s run of schedule and most commercials just get rerouted to other shows. She didn’t stand by her convictions and caved.
