Yes, ENFJs can be pretty blunt sometimes and it can get them in a lot of trouble if they are blunt with a figure of authority who does not appreciate this trait. I can say I have much experience in this and I can say I managed to piss and ENFJ off so they become like that. Or if I did, I did not know he was an ENFJ. I did talk to a girl who is ENFJ once and she was a bit like that, but I thought it was funny and cute and I appreciated her sincerity. On funny example, we had these deep talks and she told me that she loves me and I kind of got scared and said "ummm, no you don't", it was just what my intuition was telling me so she says something like: " Razvan, I'm saying this in the most loving way : Don't be an idiot, there are many ways of loving somebody". I thought it was funny, even if I was called an idiot. I did meet the ENFJ in person eventually (she isn't living in my city, she lives quite far away) and it turned out we were both right. Anyway, I was just giving an example on how ENFJs can put something that could be rude in an "envelope" to make it funny and still deliver a direct message.
