a few points that i hope will answer all questions to anyone who is really honest.
Teachings of the baal shem tov (can be found in keser shem tov as well as many other seforim from the baal shem tovs talmidim)
1) G‑d sends a soul down to live on this world for seventy-eighty years, just to do a material favor for another—and certainly a spiritual one.
2) When someone issues a “verdict” on another, he is actually pronouncing his own verdict. For example, if one asserts that because of a certain misdeed another committed he is deserving of such-and-such punishment, he is actually issuing that verdict on himself. And conversely, if one says that because of a good deed or word that another has done he is deserving that G‑d should help him in the areas where he is needing, that blessing, too, is fulfilled on him himself.
3) Just like when a person looks into a mirror and sees dirt on his face, it is only because his face is dirty, so too when someone sees a fault in another, it is a sign that the fault exist within himself.
4) Upon hearing a negative report about another Jew, one should be greatly pained. For something bad has certainly occurred: If the report is true, then that individual is in an unhealthy situation; and if the report is untrue, then it is the one who is slandering is in a poor place.
5) The greatest of the great needs to learn from the simplest of the simple—for in the simple one sees the essence of simple sincerity.
6) The simpleton and the greatest scholar share the same lofty essence: they both are G‑d’s children. Just like a child’s countenance is similar to his father’s, so too G‑d’s children are merciful, bashful and kind—a reflection of their merciful, giving and forgiving Father.
I hope this answers all attacks, if not see tanya perek 30, 32. About feeling lower than every jew even the lowest of the low, and about loving every jew as yourself.
Now before attacking chabad think of these 6 things. Very simple!
