I believe the story just a few weeks ago about Jewish boys contracting herpes during the circumcision sort of contradicts your claim. Also I feel rather certain that one or two boys experienced physical pain during these thousands of years, no? You really shouldn't make claims that are so obviously untrue. With regards to kosher slaughter: how about you present some sources? I'll get the ball rolling: A study from 2009 by Dr Craig Johnson at Massey University New Zealand found that calves slaughtered using Islamic and Jewish ritual slaughter experienced a pain response for up to two minutes (although calves normally fall unconscious after 10-30 seconds). Stunning the calf after the incision had been made immediately stopped the pain signal.
