I...I don't even know what to do with you, Lexi. Your argument, such as it is, comes from such a horrifyingly broken base that any attempts to fix it would probably drive most normal people insane. Thankfully, I'm pretty fucking abnormal, so let's get down to this shit!
First off, child, you've got a history of being a completely reprehensible twat when it comes to basic human rights. Reproduction is a basic human right, no matter how you want to "argue" your way out of it. You claim that they should be sterilized, a procedure which is, more times than not, permanent, for the safety and security of any children they might bear/sire. This is fundamentally flawed for several reasons.
One, criminality is not genetic. Two, taking a basic right for them would cause psychological damage to a person that's already dealing with or had to deal with an incredibly damaging environment. Three, there are protections already in place to remove children from toxic environments. Four, your "suggestion," such as it is, turns the standard of "innocent until proven guilty" on its nose.
You go on to assume, with absolutely no data to back you up, that it wouldn't be invasive to sterilize an unwilling convict. Your rhetoric is as broken, idiotic, and offensive as those who argue for forced ultrasounds on women who are going to get an abortion. You are invading their bodies for your own social and/or political gain and some vague "good of the many" disguise that's so paper-thin, its a miracle it isn't transparent.
Let me explain it to you in baby talk, because apparently, Lexi, you can't understand real-person speak: if you make people who do bad things unable to have kids when they don't want to, that makes you a bad person.
