I think it's understandable to have a few allergic reactions in a new environment until you get a grip on it. Especially if it's not someone's native language.

Not a strategy I recommend, but one I see often enough and understand to be benign and correctable and not necessarily indicative of problematic beliefs. It is indicative of someone needing an introduction to a facet of their communication, not someone needing to be shown the door.

Ousting people and projects from community spaces makes them vulnerable prey to the capitalist vultures. Desperation fuels the labor pool of the very worst parts of our society. Ostracization should only be done in extreme circumstances, if at all. Please seek abolitionist restoration, not retributive punishment.
