And all that does is provide the creationists a platform where they can lie as much as they like without consequence. I've never been clear on how that's beneficial.
I think just calling people liars is unproductive, but in my experience on these forums, if the lie is a documented conclusion - as it almost always is on here - I don't think it is a rule breaker. Just like it is not an
ad hominem for demonstrating a poster's ignorance on a topic.
Tale from the crypt - about 12 years ago, I was active on a forum that invited Jon Sarfati to come and 'close down' all the 'evos' who were humiliating the creationist posters there. He showed up and within the first day had violated most of the forum rules - calling people names was his go-to response.
Rather than ban their precious YEC hero, the forum admin decided to change the rules - it was now OK to call names as long as it was justified. And who would determine whether a name was justified? Why the YEC moderators, of course. And for the next few months, their forum was littered with Sarfati posts filled with name-calling directed at anyone that dared counter his assertions.
It was only when he started attacking other creationists that did not share his idiosyncratic interpretations of Scripture that the admin finally started giving his suspensions - which he did not like one bit... He was eventually banned.
Point is - Jose is right.
