Wolfish,
It is still YOUR contention. If this Mishna Brura was no longer applicable, a Psak Din is in order. You are lacking that.
I do agree that for some special situations (i.e. kiruv, a child heading OTD – with a Rav’s guidance) sometimes we put somethings aside to maintain the more important matters.
truthsharer,
There are (and I can’t quote them at the moment) Piskei Din dealing with that situation nowadays. So like I said, get a Psak Din and we can talk.
