The claim that fat is inherently unhealthy is probably too broad.

From what I have heard from doctors, there is a clear sequence:

intra-organ fat (really bad) > visceral fat (quite bad) > subcutaneous fat (relatively harmless).

The nasty detail is that some people gain relatively more visceral fat than others. These three fats are correlated, but the correlation isn't the same in every human. Some have better metabolism and don't store as much fat inside as others do.
