In a sense, I agree with you: They are dangerous, and they will probably not get better. However, I would tread carefully in the case of chronic pharmaceutical poisoning, where people trusted their doctors and got betrayed in a horrible way, e.g. OxyContin creating opioid addicts. If we can eradicate the systemic cruelty that caused these people to fall, and if we can also detox the people themselves so they become healthy, functioning members of society, I believe that we should.
which coincidentally would force us to kill a shitload of niggers and defective retards
