>> I have no idea why people would take offense to 'If you haven't tried it, I suggest you do'.

On its own it’s an innocent enough statement, and even correct. But in this context, i.e. when people are accusing you of something, and it is part of your response, it comes off as very condescending and smug.

There is a reason PR departments exist: they tend to be hypersensitive to the different ways in which a piece of communication can be perceived, and to dull its sharp edges.
