Some stats:
2. Intermarriage among Orthodox: 3%. Do you know anyone formerly yeshivish or chassidish who married a goy? In my entire life I’ve heard of only one person from a crazy home who did that. I guess 99.9% of those 3% are MO. If almost 3% MO marry goyim, how many go off the derech? Scary. So stop lecturing us about our high walls and try to learn what we’re doing right. Don’t argue with success.
