Great post. I have been in these discussions many times over the last few years. The conversation becomes thoroughly examined by all participants, then comes the question, "if someone's expressions offend your household, can you ask that person to leave?" i.e. Is Facebook or Youtube as "domain space" similar to being in" their house". That puts an additional layer into the conversation. Quite like the person who refused to bake a wedding cake for a gay couple. Was it her bakery and she can do what she wants?. Or because it is a business serving the public, the rules of equal opportunity and no discrimination apply? Even the supreme court is having trouble with this conundrum.
