As far as I’m aware nobody claims trans fats aren’t bad.
See comment by Gilch, allegedly Vaccenic acid isn’t harmful. The particular trans-fats produced by isomerization of oleic and linoleic acid, however, probably are harmful. Elaidic acid for example is a major trans-fat component in margarines, which were banned.
