In your attempt to make large "talking points," you totally take out of context some of the points the letter writer was making (which are NOT in dispute), imho.  And, you also insult,  once again, "conservatives" who are NOT American Nazis or white supremacists however much you try to weave them together leaving that impression with less discerning readers!

It is actually liberal Progressives who are "loosened from terra firma" since they deny what their own senses have told them!  Because their mindset has been so shredded by labeling people into groups (either to be used as political fodder, abused or ignored and insulted), if their senses tell them something to contradict their mindset, then they simply ignore the truth!
