They will NEVER be sucessful.
I wish that were so. We've arrived at a point where a CEO of a corporation is fired for supporting traditional marriage. Who'd believe such a thing could have happened 20 or even 10 years ago? Conversely, imagine if a CEO spouted some anti-Christian rhetoric today; what would happen? I think the answer is absolutely nothing; it would be defended as "free speech". "Free speech" meaning today's "free speech"; which is to say one is free to spout any of the current Leftist dogma.
