A couple of interesting points to consider: refined, bleached, deodorized oil such as canola oil is highly processed. Your link warns about highly processed oil in general. Considering how little we seem to be able to nail down scientifically the nutritional value of fat, the focus of the article around the role of fat in diet has a level of certitude I find suspect.
No, it specifically says that there are concerns about them and goes on to explain why those concerns are generally misplaced, e.g. in relation to the use of hexane and the amount of trans fat present.
It also explains that the levels of trans fats are higher in animal fats, especially in beef fat and milk/butter, which you conveniently chose to ignore.
As you can also see, there are references at the bottom of the page, for your further edification.
In contrast, you have provided absolutely no references to your claims, and you apparently refuse to do so.
