“Litvish is what I am, it describes my religious leanings and perhaps my family origins
Misnagdish is the rest of the family who emphatically oppose chassidik philosophy. (I am more ambivalent to chassidik thought). see the difference?”
Yes, but Chabad makes no such distinction. As you can see here, they treat it as a general term for all non-Chassidish Ashkenazim. To be honest, I thought that was how you were using it as well.
“apparently he doesn’t see it as an insult either”
That quote proves nothing. He’s clearly using it in an ironic manor like I was when I called RSo an “evil misnaged” earlier on this thread (or perhaps one of the other ones; I can’t keep track).
“so it is OK to define oneself as negative to something.”
Sure, it’s “OK,” but it’s silly and kind of sad. We COULD have started identifying as “Anti-Christians” two thousand years ago instead of continuing to identify as Jews, but we didn’t change our self identity on the basis of sectarianism for hopefully obvious reasons.
