A ban on christianity?

I’m not the type to believe that one group of people should tell another group of people what they can or can’t believe, this is just a way to open a dialogue about a subject that people can get quite touchy about. Would the world be a better place if Christianity in all forms was outlawed? I’m not talking about religion in general, specifically Christianity. What would change? Would we be better off? Would it make any difference to you personally?
