While Aisov may not have been a known wife-beater, he was a murderer and an aduterer (is that a word?)
I’m not necessarily disputing that point. But the point was made that protecting your daughter from a wife-beater is bad because of what happened to Yaakov and Dina. My point was meant to show that Yaakov was not necessarily punished for keeping Dina from a wife-beater since we don’t know that Eisav was one.
