Both sides of the spectrum have their own version of political correctness. On the left, it includes being sufficiently sensitive to minority or traditionally marginal groups (among other things), while in the right includes being sufficiently patriotic, including showing expected respect during pledge of allegiance (you'd think the Kaepernick thing was the end of the world given how some on the right were in such full frothing outrage over it) or showing expected deference to authority, partiucularly police and military, or showing due respect for POTUS (at least now that Trump is in power, not so much under Obama).
I think both sides could probably due with relaxing the sphincter a bit and adopting a bit more of a live and let live approach. Way too many people getting outraged about way too many things. I just don't know how some people can enjoy life at all with how easily and frequently they are outraged all the time.
That's the thing. You can't call yourself a liberal, then act like the nationalists and the fascists. If you believe in individual autonomy and the importance of free discourse, then you're a liberal. If you believe that people who have "dangerous ideas" should be denied a platform (and much else), then you're not a liberal. So stop calling yourself one because you're making the rest of us look bad.
P.S. none of the "you"s in the response is intended for jej or anyone else. It's just a substitute for "one".
