This is your explanation for calling it a "troll video"? Did you watch it all the way through?No. They refused to make him a specialized cake that they don't normally make. They did not refuse him service on the basis of him being gay. Find a video of a Christian being denied service by a gay vendor, just for being Christian, and you'd have a valid comparison.
You obviously didn't, and this speaking out without having an understanding of the facts is a problem with ALL leftists.
