These people aren't asking anything to be censored, or asking for anything that would affect what you see. They are merely asking for a way to filter what goes into their own eyes and ears. Why are you bothered by their request. That is as silly as getting upset with someone in a restaurant who asks not to be seated under a fan because they don't want to be chilly or not near a window because of the glare from outside. It's ok for you to want to not be restricted in what you can watch, and it's ok that they want to not be restricted in what THEY watch.
