He Isn’t Banning texting just eradicating its obsessive nature,
lack of respect for one surroundings,from penetrating his beis medrash.
One cannot ban something that in itself isn’t wrong.
Like wearing a bathingsuit is fine, but not in beis medrash.
If I could I’d ban anyone from entering a shul with a cellphone
unless it was off, set to silent or vibrate!
