RABBI Angel is as chashuv as they come, and his commitment to torah and mitzvot is unquestionable. His ideas on giyur are rooted in the Rambam, Shulchan Aruch, and Rav Uziel, zt”l, and if you wish to be frummer than the Piskei Uziel, Mechaber, or Rambam, that is your prerogative.
Show me one credible source which says that believing in scientific evidence is apikorsus, or that there are ideological litmus tests as to who can sit on a conversion beis din.
If you assume that evolution is apikorsus, and a rabbi who believes in it is pasul, than you just slapped so many gedolim in the face, Rav Kook and Rav Hirsch included.
Others don’t have to be wrong for you to be right. This religion of triumphalism and one upmanship is not what G-d had in mind when He gave us the Torah and it is certainly not what they had in mind in Sura and Pumbedita.
