@Kuvult: At the same time, we must learn to separate the Jew from his ideology. Just because we love and accept the Jew himself, that does not mean that we agree with him whatsoever.
There are times when children must go to separate schools because of different chinuch standards. This does not mean that the Chasidish Jew looks at the MO Jew as any less Jewish, yet he doesn’t want the MO education and values to be imparted to his son.
Moshiach will come no matter what, but we will definitely bring him faster through:
1) holding on to our own derech without bending one iota, and 2) overlooking the differences between Jews, and loving every Jew as a true brother (the fact that you don’t agree with your brother doesn’t mean you love him any less).
