Pederasty is so far from our cultural norms it’s current form is meaningless compared to a socially accepted version. In a society with active mentoring of youth by people across the gender and sexual orientation spectrum pederasty would reduce the stigma’s associated with homosexuals thus increasing social cohesion.
War is a stress test for societies. By destroying less efficient social structures it promotes long term progress and reduces inefficient practices like slavery.
Heroin is an opioid and can be used as such. It’s current stigma is associated with recreational uses, but it can easily be used for chronic pain in a hospice instead of similar opioids.
PS: IMO the real reason to segregate ideas across forms is to avoid having the same conversations everywhere. Bringing up politics means people talk about politics rather than whatever the original subject was.
