Having a bad morning eh? Not sure the reason for the hostility.

I simply stated that I thought granite was denser than other kinds of rock I commonly climb on - based on my gut feel and limited knowledge of geology (highschool level, some internet reading, talking to some actual geologists and basic reasoning skills).

I backed this up with some links stating that yes, granite is denser (which is what I originally said).

I'm not really sure what point you are arguing here, or who the "ignorant internet poster"/"garden variety retard" is....
