Been seeing more and more of these but can't find a source and after a cursory glance at your database I couldn't find it. I can't find many quotes but this is at least the 4th time I've seen one of these threads unfortunately I didn't save any of the others. This one I just saw in an unrelated thread on 4chan figured it might be an idea to keep an eye out for more.

The general format seems to be a 'relatively' innocent phrase apparently uttered by Zach followed by -Zach Braff on [Horrible Event/Controversial Issue]

The two examples I've found are:

“I really see no problem with it. At least half of the people involved are enjoying it. Why spoil their fun? --Zach Braff when asked about rape.

"I believe that the best course of action is to gather these people together in a concentrated mass in order to purge them from our world in a cleansing fire." Zach Braff on people with AIDS.

I'll keep it updated if I find any more :p
