Wait! Wait! The Litvaks built their yeshivos on the premise that by the time their sons are bar mitzva they would have completed most of chumash with rashi as well as the mishna. I could go on, but the point is that knowing Kol Hatorah Kula was a given by the Litvaks. Also learning slow isn’t an issue.
Rav Chaim didn’t actually write what the OP claimed. The Litvaks considered those that forbade shavers to be completely wrong on the issue. It’s not worth debating because all the militant ignorami come out with their nonsense. If you like your beard you can keep it. I’m taking it away from you.
Being at your gemara before dawn is an excellent way to be prepared for davening. Litvaks have a full chazaros hashatz at their workplaces. I know several Litvaks that do not leave their gemara to daven mincha with a minyan. If no minyan shows up, they daven alone.
I would like to point out, that the OP has not posted since. It’s not about Chabad as much as his own thin skin. Every group has their issues. Okay, outsiders don’t get Chabad. They are not expected to. They measure Chabad by their own standards, not Chabad’s standards. Why is it a big deal to you if you claim to only know Chabad?
