This is what I don't get. If every time we quoted a source or referred someone to a good argument made by someone else, we had to confirm we agreed with every single idea or viewpoint that source or someone else had ever been a proponent of, no one would quote anyone or refer to any sources.I happen to agree with Robert Florczak's remarks on the deterioration of modern art and the incredible stupidity of much of what hangs on the walls of museums. I also happen to disagree strongly with the politics of PragerU. I can assure you that many, many other people hold such (to you) anomalous positions.
Although I'm of a more right-wing bend, I still think most of the PragerU videos are vaguely factual garbage; however, I too happen to largely agree with this one video.
