There really is no such thing as a "pro seed oil" troll. He's pointing out gaps of evidence in the common claims that people who vilify seed oil, which is a real thing. If someone is making the claim that certain foods are deleterious, there has to be strong evidence to back those claims. And on a cursory glance, I'm not convinced that seed oils are deleterious. By all means though do your research. This is one source, but I've read others as well.
