Enforcing a set of beliefs based upon destroying or enslaving anyone who does not profess those beliefs is today at war with freedom of the individual. It has now gained the respect of the title: "war of ideas."
How different is this to:
2 + 2 = 5 is warring against 2 + 2 = 4. We cannot refer to these as right and wrong, no, no. Each one must be respected as having its point of view.
