Fair comment curiousconfused. It was a pretty broad sweep. Of course not all, indeed probably the minority, are knowingly and consciously selfish or otherwise "bad" people however the indoctrination envelops those who are mentally in with a set of behaviours that legitimise a cultural selfishness. I was under the spell at one point and so was everyone else whilst our thinking processes, logic and reason were filtered through the WTS brand of religious justification.
So, when my wife criticises me for supporting certain charities I call her out on it. She not a heartless person, she can empathise with the suffering of people round about but she is caught in that reasoning that says it's OK for Witnesses to do nothing significant to help because it's simply a sticking plaster on a gaping wound.
I agree with you about attendants as well, I've done the job many, many times and seen first hand the worst of behaviour and the best of behaviour from both attendants and attendees.
Whilst it is fair to point out the generalisation, the point of the post is not really to condemn every person but to call out the culture that allows otherwise selfless people to have their thinking conditioned and manipulated where they cannot see the wrong in their own behaviour.
