I have more of a problem with someone insinuating that someone else is faking or tries to call them out in front of others instead of speaking with them privately. I have felt called out before in front of many others and that lead me to questioning myself and having some real problems for two days with my illnesses and ultimately made me want to leave from the place where it happened. If anyone ever thinks that someone is faking anything like that and feel that they must say something then, the best way to do it is one on one in private. Anyone who can't be discreet about such a thing has no tact.
