I think I understand what's going on here. You think you are helping the situation. You think that because you've identified what you find wrong with a few people in this community that you are somehow qualified to stand above the hoi paloi and administer a little dose of "what they need".
The way you talk: "As a former mod", "a little tough love", "a whole world out there about to eat them alive". It suggests to nearly everyone who reads it that you think you're pretty special.
The truth is, you're just a dude on the internet, like the rest of us, who has an opinion on something. Flashing your credentials and talking in a paternalistic tone doean't add weight to your message, it exposes you as a self important dude on the internet. There are more than enough of those to go around.
No need to start a whole thread - as a former mod you ought to know that.
