There's a big loophole in this, and that it's reversible (in case of chemical) or not followed through (surgical). In the former case there was an episode on Dankula's channel about a jewish pedo murderer (an oxymoron I know) who had connections with the doctor who had chemically castrated him, so he just had him undo it and nurse him back to health. And what do you know, not even a year later he was doing the same damn thing again.
