I know you think what you're doing is "elevating" conversations, but ... "calling out" people for the slightest bit of negativity is an extremely toxic behavior. Quality discourse requires negativity and fosters a healthy span of tolerance for it. Your interpretation is also very narrow and passive aggressive itself, to me it seems completely neutral that in a case when someone has a strong opinion based on ignorance, you remind them of their ignorance - not just for people reading it but for their own sake.
