Chabad believe that the rest of klal Yisroel are missing out on what they call the "penimius hatorah". If they really think that everyone else is seriously lacking in Torah and yiddishkeit, the next logical conclusion is, that a chabadsker that is a real ohev Yisroel should attempt to be mekarev kerovim.
This theory is backed up by years of circumstantial evidence.
They clearly have a mission of " uforatzto " etc to spread their version of chassidus... They talk about it all the time. Even here on Ddf! Those people who offer to learn "chassidus" with you are just doing uforatzto.
If this what chabad teaches and you believe in it, why deny it... Embrace it!
I personally respect the sentiment. But I also respect satmars right to say no thanks.
