You attempted to claim that such overdoses are in part due to Reddit (and society in general) ostracizing neo-nazis and members of hateful groups. Not only is this just wrong, it implies that many affected by the crisis are members of such groups, which they are not (as someone who has a family member addicted to opioids I'm very annoyed by your comparison).
You just wanted to talk about your Neo-Nazi subreddits getting taken away and people called you out on it. Frankly, a Neo-nazi should be an outcast. A racist, sexist, etc should be excluded. And if they don't like that, then they should stop being a Nazi before turning to drugs.
