"Yeah according to me, actually everything I'm posting on this site is my opinion"
Correct. The first thing you've stated that is correct, void of all objectivity.
"and if I reach 150 replies in 24 hours I'll probably tell myself it's time to do something more productive"
Incorrect. Being active on a forum has nothing to do with lack of productivity, that is according to your intrusive opinion as a whole. Think before you type, do not judge others of having no life merely because of posting on a forum. There is no need for such objectivity and malicious assumption as it's fairly easy to max out 150 replies, if you're an active poster.
You are not, therefore your opinion as a whole is invalid, but respectable (to an extent) regardless.
Do you understand now? How immature you're being? Let me remind you: "if you reach that limit you need to question your life"
Utterly garbage presumption.
