The Chief Rabbinate of Israel has taken a restrictive, hareidi view on conversions to Judaism. They have imposed "standards" that are unrealistic for many would-be converts, and which are not required by the halakha itself. The Rabbinical Council of America has essentially capitulated to the Chief Rabbinate, and is now in the process of establishing regional courts in the U.S. and Canada that will adhere to the extremist opinions relating to conversions.
Some time ago, I was in an airport waiting to board a flight. A young Orthodox Jewish couple was sitting a few rows in front of me. He was wearing a black kippah, and had tsitsith hanging down the side of his black pants. She was wearing a blond wig, long sleeved blouse, and a long skirt. At some point, she arose and took out a pocket prayer-book. She shuckled quite conspicuously as she mouthed the words of prayer.
