Menachem: If anyone thinks that majority of Lubavitchers wear yechi yarmulkes or majority of Chabad kovtzim say yechi on them – they are plain ignorant.
You may be right numerically, but not as far as publicity goes. Wherever you go in Israel you see Yechi signs and stickers, and in the most annoying places. It is also the ones with the Yechi yarmulkes who put out all these crazy videos etc.
