What gets me is the "that's not my experience" aka the "I ve never seen that" argument. A close relative of the "I know nice such and such people" argument but just as irrelevant.
As has already been said, assessments of ideologies are not dependent upon such things as "niceness" or politeness or limited personal experience or whether the uniforms are cool (hyperbole with that last one).
Does it matter that JW parents were "sooo nice" about it as they allowed their child to die when blood transfusion would have saved them? Does it matter if the mafia goon that executes you is such a gentlemen? Does it matter if the kkk have great bbqs and picnics? None of those things have anything to do the ideologies of the group, in fact many of those groups use "nice" acts to recruit, effectively honey-trap people into coming on board with their evil ideologies or lulled into tolerating abhorrent teachings.
The niceness factor is a distraction trap from the real issues.
Now, can you all stop violating me with your differing opinions.
