South Park has never really seemed off on gay rights/issues/acceptance. In commentaries the two have talked about how they grew up with a lot of gay kids and they've never seen it as anything but normalcy. The biggest issues SP has ever had was with their weird messaging on trans issues. I don't even think the two are transphobic(I don't think the garrison/dolphin stuff was even transphobic beyond being stupid, crude humor), they just can't make any good points on it.Maybe you're right, but remember that Matt and Trey are completely fine with gay people. If the boy scouts want to do their quasi religious bullshit then we're all better for not joining them, and the message is more that you'll be consigned to history if you're not willing to update your views to accept widening demographics. They probably could have said it better, but the very fact that they painted the boy scouts as illogically homophobic throughout the whole episode sets an updated standard. So if that baker is going to discriminate, more and more people of diverse and accepting philosophies won't go to that bakery. In that sense libertarianism does shut out socially and morally regressive businesses.
