It is good to put rules but mind you this is a social network, we exchange views and we share views. Like any other social events if you feel that someone is telling lies, you tell him/her that the truth is this or that and not to moderate his/her speech. The era of moderating speeches (era of communism and fascism) is gone for now we live in the slogan of French University Students After the Time of France Revolution, their slogan was 'IT IS PROHIBITED TO PROHIBIT' Who is empowered to switch off the minds of others? No one but none is equally prohibited to choose his/her views and viewpoints.
