The opening poster partially answered his question in his last sentence, i.e., some frum Jews support any nonsense that liberals oppose. Another part of the answer, I believe, is the mediocrity of science education in yeshivas. And a different part of the answer is the failure to educate ourselves about how to reconcile the teachings of Torah with the teachings of science.
There is a journal dedicated to the interface of Torah and science, edited, I believe, by a Chabadnik named Yermiyahu Branover, who is a scientist educated in Soviet Russia, who became frum when he left the Soviet Union in the early 70’s. If you want to genuinely learn about Torah and science, find that journal.
