It seems there a quite a few judgemental christians on freerepublic and they judge without any real knowledge...I remember someone saying "judge not least you be judged". And you gave a perfect example of insulin for diabetics...As a nurse I have seen those that did not take it serious until they had to have a foot or leg amputated...
It makes some people feel better about themselves when they denigrate others. Sometimes i wonder if they're bullies in real-life, 'cause the behavior is very similar.
