I updated my Sdei Chemed post. I also noticed another letter in Igros Sdei Chemed to the Maskil Shmuel Abba Horodetsky protesting his citation of the Maharshal's harsh coments against Beis Yosef and others. I was surprised to learn that Horodetsky has a letter published in Sdei Chemed here (lower left column). There is also a letter in Sdei Chemed from the (later to be) Israeli Minister of Religious Affairs, Y. L Fishman (Maimon).
