Thanks for your lengthy comment. You have no idea how much I appreciate it, because it really has all affected me deeply. And when I see comments in support of the Jewish people - few and far between as they are - it means a great deal.
Yes, the level of denial is disgusting. People who are clueless choosing to claim that these atrocities likely never happened. I don't know, maybe they think they look "cool" by promoting posts that push the narrative that everyone wants to see, forgetting that they may have friends who are Jewish and/or Israeli. Forgetting that they are human beings too.
