“More than that. We are allowed to ignore their opinions. Especially if it absurd.”
This is in direct contradiction to what you say earlier in the post. If he makes his beliefs public like in the case of Jews for J, it’s an issue that you can’t just ignore. If you’re dining at someone’s table for a Shabbos meal, and he admits “I actually believe there are 5 gods and 3 goddesses that created the world,” you can’t just label that as “absurd” and continue eating his food a pretending he’s acceptable in the frum world.
I’m not answering your questions about Chabad, as I stated earlier I don’t want to be a part of the Chabad war on this thread anymore. What you’re implying at face value has the potential to be far more problematic than anything Chabad does or believes. However, you only seem to apply to Chabad exclusively and no other group or belief-system.
“I have never been shy about this topic and nobody felt required to stop me at all costs.”
I’ve had people say insanely kefiradik stuff around me in-person, and I don’t stop them either, but right now you’re on the internet, so you get to hear what all those people who “didn’t try to stop you” actually think of your shittos.
