What if their religion does impact on others - like Israeli footballers?Why should a person's choice of religion be an issue? The fact that a person chooses to believe in GHod does not mean their beliefs will necessarily impact on you or anybody else in a negative sense. I have no time for fundamentalists, but because a person has their faith as the guiding principle in their life I see that as not being a problem as long as they are not thrusting their beliefs down your throat.
You may scoff at them and as you call it their imaginary friend, but my attitude is live and let live. I have learnt that some people use their religion to further their own agenda by what ever means necessary, but not everyone is like that.
Thanks for your permission to scoff - I guarantee you I'll make good use of it.
