Feif,
Not a bad idea to leave the CR, but probably for the wrong reasons.
I for one, who consider myself anything but MO, do not harbor an ounce of hatred towards MO Yidden, although I may strongly disagree with them in many areas of hashkafah. All of my peers, fellow “chareidim”, feel the same way as I. The sinah occasionally posted here is not a reflection of the real world (in fact most of the people in my peer group don’t even have regular internet access). this is a good reason to either leave, or at least not partake in these types of discussions.
The silly posts you saw here were probably written just to elicit the reaction they did. The bored bochurim who wrote them are probably giggling at your response.
Hopefully, you’ll use the time, otherwise spent here, doing more productive things (which is the other real reason we should all leave).
Be well!
