[marto]: LanX yesterday I found out about Gish gallop tactic
[marto]: "Eugenie Scott, executive director of the National Center for Science Education, dubbed this approach the Gish gallop, describing it as "where the creationist is allowed to run on for 45 minutes or an hour, spewing forth torrents of error that the
[marto]: evolutionist hasn't a prayer of refuting in the format of a debate." She also criticized Gish for failing to answer objections raised by his opponents"
[erix]: one would hope evolutionists haven't any prayers anyway
