Let me put it to you this way: Let’s say this forum was full of Open “Orthodox” Jews who look and sound like regular frum Jews, but honestly believe in things such as intermarriage, toevah marriage, and shechita as a tzar ba’alei chayim issue, there would be no end of posts of Torah Jews arguing that they are mistaken and their beliefs are not what frum Yiddishkeit is about, in fact quite the opposite. We wouldn’t hate them. We would just be upset that they were raised to believe in things that are contrary to the Torah and believe that following those things still makes them frum’eh Yidden.
That’s how the overwhelming vast majority of the frum oilom views Chabad-Lubavitch.
