Ok I know nobody cares a jot if I KF them . As is I have KFed no-one in this group but I feel I have to to weed out some of the OT chaff on here. Harry I'm looking at you.
I have seen politics ruining many groups, even in quiet times do not post political stuff as those who happen upon the group see all these political posts and think this isn't a DIY group at all it has become (like so many others) a political group and so they don't post. No incomers means no new blood means the death of the group.
There are gazillions of groups who deal specifically with politics use them or if (unlikely as this is) you cannot see a group that deals specifically with your particular interest make one (not that hard and I am sure it would be fairly easy to find a "how to" via Google).
