Isnt it offensive to assume that devotees critical of Mayavada are motivated by ego and to not associate with them?

From Sumed Pr:

I have a doubt come up in my mind after hearing your answer to this question which I would like to humbly ask here. You said in this answer that (paraphrased) “we don’t have to associate with devotees who are strongly critical about mayavad, its best to keep a distance from them,and there are so many other things to discuss in our devotional practice apart from refuting mayavad” could you please elaborate on this? because what I heard so far that all the vaishnava acaryas were strongly critical about mayavad so if some devotees want to follow on footsteps of such acaryas and so will it not be offensive to isolate such devotees from our association? is it safe to assume that such devotees are doing it always out of sense of ego and not out of devotion at all?
