If I find shocking is that people expect this to turn out any differently than the joke facebook drive for Floridians to shoot at the approaching hurricane to try to divert it. Nobody who actually signed up on the facebook page or voiced support was being serious and nothing did end up happening. The police did issue a warning to not do this, but then, they have to worry about there being just one nut who might take it seriously......
Anyway, your article asserts :"it’s anticipated that thousands of Americans in at least nine cities will take to the streets to iscream helplessly at the sky'", but doesn't provide any citation. It then only seems to talk about NYC, saying "Nearly 2,300 people have already signed up to scream helplessly at the sky in New York City, and 15,000 more have expressed interest." Unlike the article at the start of the thread you previously started, they don't deign to cite to a Facebook page. At least I know that with the other one, it was canceled within three hours. Sadly, that didn't stop people from acting like it was a real thing that reflects poorly on liberals generally.
So instead of running around trying to rib everyone identified as being "on the left" with this, I'd suggest waiting to see whether any of this actually ends up happening and how many people actually show up. And then, I'd suggest making an honest decision about whether you will hold yourself responsible for everything done by similar-sized groups of people on the right (or, to be most fair, to hold yourself responsible for everything done by similar-sized groups of people of whatever political persuasion someone feels like identifying you with).
How about that? Seems a lot more fair to me than constantly throwing what is still quite likely a big joke in the faces of various people on DP who haven't expressed any interest in attending....
