Well that's quite a meaty response to consider, what with you firing off questions rapier like at me without actually pausing to give the answers sufficient consideration yourself. Some of us on this site are actually engaged in gainful employment so why don't you be a good fella and use all that free time you have to find out the answers to these questions yourself seeing as it's your argument that depends on them. It's one thing to criticize someone for using empirical evidence and question the true value of that evidence but it's entirely another to provide no evidence whatsoever for your own arguments.
