The example of the left hand wiping the bottom is from Islam.  No mention of the left-handed, what do they do.  No mention that males hold their penises when urinating and rarely wash their hands after urinating.  And Lex using a female as his example of the "darkness of human nature" is sexist and misogynistic.  Reisman should refrain from attaching gender pronouns when giving examples.  And saying he was smitten with a "beautiful" med student, later attaching "her".  Why do males label females beautiful when they are attracted to them; females don't indicate males as handsome.  Why would Reisman say ".....brilliant and perfectly designed by evolution or whoever ...."  Whoever?  Once again the male ego strikes because there simply has to be a who that designs brilliance and perfection.  So, in the discussion regarding human genitalia only the uterus is discussed at length (by these two males), nothing about male genitalia, (until discussion about improvements and males worrying about their balls which most don't have), which is the cause of so much violence against females.  Lex moving on quickly from penis to vagina.  Wonder how many males would opt to have children via an artificial womb?  None, because then males can't blame females for trapping the male into "supporting" their children and getting pregnant to steal all the males money.
