Dietary Fat is not bad for you, neither is it the same thing as body fat which is an indicator for excessive energy intake (most often from sugary drinks) and being generally misinformed (99% Fat Free? Awesome! Nevermind that added sugar to cover the lack to flavour we took out). What is bad for you is too much, EXCESS. Except this goes for everything. Such as too much sugar, protein, hormones, almost any drug & water can be a detriment, even lethal to you. I'll only give you that trans-fat is terrible.
The market hasn't and never will teach you that moderation is healthy because it's against their business model of selling excess. See meal portion sizes and how they have increased over the last few decades. I hope you're not taking fish oil supplements as well. Anything with this much marketing behind it should be cautioned with much skepticism.
Edit: I stand behind my criticism of anti-fat culture.
It is more likely that you are down voted as you went on a rant about fat to a parent who was talking about consumer tastes I the 80s and 90s. It would feel that both these replies are likely noted as off topic to the general conversation going on here.
