I have been approached by different groups who suffer terribly because they are looked down upon. Sometimes people rely on Gedolim’s: הִ תְ נַ גְ דוּ ת opposition. However, I myself heard from many other giants in Klal Yisroel who were either more liberal or even supportive of certain “inferior” groups. This area is super dangerous, because you have a well-known Fruma Yetzer Hara supporting your “Shitos”.
What you think is a big Mitzva may be your worst Aveira. They say in the name of R' Yisroel Salanter Zatzal: כָל מַחֲלוֹקֶת שֶהִיא לְשֵם שָמַיִם, סוֹפָהּ לְהִתְקַיֵם אבות ה יז Your “holy” Machlokes will remain, meaning that if you are "L'shem Shamayim", then you’ll Chas V'shalom always be fighting (and help destroy Klal Yisroel, Chas V'shalom!). In Novardok I heard “Negi'a Gaon”, i.e., you are a Gaon in your Negi'a and you can prove your “Shita” right with: ק"ן טַ עֲ מִ ים 150 reasons.
Your Negi'a comes from your background, and you are only a puppet of what you’ve seen and heard. It may pay off for you, since you come out being the “good guy”! You have no idea how tricky the Yetzer Hara is in this area. Sometimes it would have been K'dai to be a lowly Am HaAretz without all your Gadlus in Torah and Chesed, since you wouldn’t have enough Ga’ava to become a Baal Shita which is so detrimental to Klal Yisroel and the Geula Shleima.
Ayin Tova Is a Big Teshuva, And Real Shviras HaMiddos
Learn to “lie”, like R' Ahron Belzer Zatzal, even if you’re wrong in your seeing “only good’ in questionable people. It can have a major Koach in Shamayim to bring Yeshuos and Refuos: בְ לִ י שִ יעוּר without limit.
Ayin Tova is itself a big Teshuva, and a real Shviras HaMiddos. In Novardok I kept hearing how in the army of Achav HaRasha didn’t lose despite their sins, since there was no Lashon Hara. (Yerushalmi). And by Shaul HaMelech they were Yi’rei Shamayim, and yet they fell in battle because they had Lashon Hara. Understanding people who are not your “type” and being Dan L'kaf Zechus can surely bring victories for Klal Yisroel! Hamas is built on the nature of humans to have a lust for hating others. We make sure not to get even a drop of that Midda, or else the outside world could magnify our subtle distaste for other Jews, Rachana Litzlan, and we have Milchamos!
