On one hand, as mentioned above, people make discuss here issues that they will be uncomfortable to mention in person.
2nd, I have a similar question in reverse: those Chabadnikim who sound reasonably in public – do they also chant moreinu .. when they are surrounded by only their own?
3rd, I would prefer to rather discuss Chabad great work with under-observant Yidden, and how others could join or learn from that, rather than all these shtuyot. I wish other Yidden discuss THAT even when they are not near Chabadnikim, but I rarely see that.
4th, rejection of Chabad by other groups is not based on recent events, it was there when L Rebbe Z’L was alive. Whatever the particulars were, the main basis is not joining the main opinion, same as with others who are not counted.
