"For those unaware, CloudFlare was providing proxy shielding of ISIS's propaganda websites"
If the business owner was Christian and decided to ban pro-gay marriage websites, would you be fine with this?
The problem is that when we start deciding who gets the freedom of expression/speech, it starts to erode the rights of anyone that doesn't agree with the status quo..and the people with the most money and power get to decide what speech is moral/immoral.
HN is a good example of it in action. Even comments slightly off the standard SF ideals gets down voted and silenced.
It's a scary time for our country because it's almost like we are slipping into fascism. If you have an opinion that is against the current narrative, you get silenced, your career is ruined, and your life is destroyed. Bullying is also okay in this situation. Nobody can just disagree anymore. Opponents need to be forced into submission.

I think it's great that the CEO of CloudFlare took this stance. It takes a lot of balls and I know when the time comes, my speech will also be protected.
