I wasn't going to go down the rabbit hole since you seemed so sure. But once I decided to, it was kind of fun. I first searched your user name and the word "Klam". It brought up a ton of hits, and I'm flattered.
I then switched to "the left" and found this one where Chizzy chastises you for hypocrisy and pretty much doing what I said.
Now I'm sure you'll argue it's not exactly the same but this was only after a few minutes of searching just two key words/phrases. If you'd like, I can go try searching words like "liberals", "progressives", "doctrinaire" etc and find some more examples if you'd like.
There's only one problem
The "left" HAS been losing their collective sh1t, just as predicted. And the hair pulling isn't coming from the fringe - it's coming from up and down the spectrum. I even have colleagues- former tut-tutters, Georgetown and Harvard educated progressives - who thought those "Obama is a Muslim" flyover country bumpkins were so dramatic
Now they're in full "the Nazis are coming let's head for the hills" mode
Almost to a man- and they're all publicizing the protest marches they are going to in a few weeks.
So the original post and my reply are strangely prescient - Clitzstain's 'yes but conservatives do it too' allusion notwithstanding
