Baali teshuva ( newly religious-) in spite of their supposed loyalty to Torah, are traitors to their parents. And a traitor once- can be a traitor twice. In fact, this is the reason for the general lunacy of the religious world. The fact that people who are newly religious and traitors to their parents are also traitors to Torah and they pervert it. And this is the bulk of the religious world- that neither understand Torah nor are loyal towards it.
They might have asked themselves before they jettisoned their loyalty to their parents: "What to do with the fifth commandment?"
[The issue was noticed long ago and was the reason Litvak yeshivot did not accept newly religious in knowledge that the newly religious are flakey. That is--they can hold with all their might and soul to one opinion today, and to the opposite tomorrow.]
