I study Gemara about seven hours a day and that sharpens the mind. Your expression is very strange, “I’ve never in my life been a Lubavicher.” If you’re not Chabad just say, “I’m not Chabad.” The fact they you gave such a wordy response calls to mind the Bard, “Methinks thou doth protest too much.” Yes, I’m pretty sure you’re lying. And even if you aren’t Chabad, you’re lying about Chabad not telling people to remove their shoes at the Ohel. I know because it was personally said to me and my credentials for honesty are well established.
