Am I exaggerating? Maybe. To be honest I don't think I am. Creationists very often refuse to even the possibility of being mistaken. Something I always have a problem with. No matter who makes what claim. It's far too arrogant IMHO and smacks of fanaticism, not faith.
Part of my problem with it is that we often see creationists cone into contact with scientists or engineers or just people with a decent amount of knowledge, only to make complete and utter fools of themselves by claiming something outrageously wrong, for example the moon-landing dust scenario, the entropy argument, the conservation of angular momentum argument, a plethora of other severe mistakes which they then vehemently try to associate with Christianity. Effectively alienating Christ from the other part of the discussion. In effect making faith borderline impossible to the person in question due to this poor approach. St. Augustine covers this very well in confessions btw. Good book.
Yeah, we are not supposed to be like this world. But don't you think that's about loving where others hate, forgiving and showing compassion? And don't you think that when presenting a position which theologically is held by only a few some humility should be present in the claim in case the claimant is wrong and hence inadvertedly works against Gods plan?
That has happened soooo often. Christians who claim perfect knowledge and bungle it majorly instead. Look at the geocentrists for a brilliant example.
