“teach Gemorah to ladies have significant names and arguments behind them”
My rav o”h quoted Rabbi Joseph Soloveitchik z’tz’l as saying that it was a chiyuv to teach gemara to women. And one of the few halachic statements we have from him in writing is one in which he orders a school to all their limdei kodesh classes be co-ed. He refused to give that psak until the school leaders agreed to follow his psak no matter what he said. And of course he himself founded a co-ed school.
Obviously there are those who disagree who have the stature to do so. But I suspect that none of them comment in the YWN comment fields.
