...highly processed..."
I think this is an important distinction for evaluating oils. For example, you mention avocado oil and coconut oil. Are these processed with heat (and possibly solvents)? Or are they cold-pressed with no other chemicals used to aid extraction?
In the UK, it is very common to find cold-pressed rapeseed oil (canola oil) in supermarkets. The canola oil sold in US supermarkets is highly processed. Is the cold-pressed version still bad?
The problem is that when seed oils are demonised, no distinction is made of the method of extraction. There are hundreds of researchers (and YouTubers) repeating the mantra 'seed oil = bad' without further distinction between heat-pressed and cold-press oil extraction. If extraction methods don't matter, then researchers need to provide evidence to confirm this.
