Complete nonsense.
The merits and demerits of circumcision are completely moot debate tied into a primal fear and insecurity.
Plenty of perfectly healthy and functional circumcised males exist. Plenty of healthy and functional uncircumcised men exist. The whole "debate" is meant to cause men to fear their masculinity has been compromised while attempting to empower a class of people without any merit or evaluation.
Put simply. "If you are circumcised, then you are damaged goods and are never going to reach the best you can ever be. You will always be inferior to this nigger over here."
If there is a Jew conspiracy, it is to spread circumcision among a population and then create a fear campaign to delegitimize those circumcized while elevating barbaric Invaders within those societies as morally superior to the native culture and male.
