It could be an opportunity to take the high road.
Instead of the attitude that if someone starts something with us we'll start something back.. Just let them dig their own graves.
It's college and most people can see this for what it is. A crappy chapter's attempt at making themselves look better at the expense of another. Just ride it out... When it comes to rush you'll end up with the guys that were turned off by all the BS they were spouting.
No worries man.. if the BS is that thick people can smell it a mile away.
Or you could always just burn their house down
