I take your point Ed, but you have to allow for context. Any statement relating to personal preference can hardly be supported by objective evidence and to demand such evidence would be, as you point out, pointless. However, a statement such as 'young earth creationists pose a significant threat to society', may or may not be true but should, I believe, not be allowed to go unchallenged because some may feel that YECs are generally harmless if self-deluding people and disapprove of singling them out for opprobrium. A good way to challenge such statements is to ask for evidence to support them. That way a reasonable, objective debate can take place (provided one ignores the spittle-flecked hatred spewed out by a small minority who see personal abuse as a valid debating point - obviously).
