We are a friendly, inclusive and informal group who enjoy lively discussion, however recent events have led us to require a 'Let's not got There' type of rules thingy;
Namely, we will not tolerate racism, anti-semetism, sexism, or any other form of discrimination or have our group used as a sounding board for any such groups or individuals who would be likely to cause offence by trying to air such views.
That's all common sense you would think, but it has needed saying.
