I think what Ian a Steve need to understand, is there are hundreds of people in this forum, many do not take part in the discussions, but are happy to read and feel part of the on line community.
It is not all about THEM and what they can tolerate.

Folk should be able to come on here and express reasonable views without being immediately attacked in an aggressive and personal manner.

None of the issues we have been discussing are simple, but some people will condone nothing but their view of the world to be expressed. It is disingenuous to promote the idea that these issues can be solved by adhering to simplistic ideology.
Open and frank discussion of the subjects is what is needed....not an "odium barrier".....that does deserve to remain in the armoury of the facsists.
