What do you all think about “seed oils”?

If you have spent anytime online, you know that “seed oils” are out and animal fats are in. It makes sense to me that consuming high amounts of refined omega 6 rich oils in the context of the standard American diet is probably not great for health. However I remember in dietetics school that a lot of the research suggested that people should replace animal fats with seed oils and that they are actually beneficial.
