The problem that i usually saw on some communities like Linux or Tech in general is that they're dodging whatever that makes them disgusted or hate to talk about.

Especially when someone talked about it, They decided, "Let's not talk about that." and then deleted your message. The problem here is that you don't know what does that actually mean.

It won't make people stop thinking but rather ended up being more curious, and that's the biggest problem itself.

(need to know about human psychology even further?)
