Trolls always try to wrap their attacks in semi-agreeable contexts so it doesn't get immediately dismissed and can enter mainstream channels. That's the whole idea. Similar to how activists try to wrap everyone who disagrees with them as mere sexists/racists/etc to give their arguments weight and credibility in those same channels - usually using the troll's purposefully provocative behaviour as their evidence and justification.

It's an increasingly popular phenomenon that we need to be conscious of as a culture and not give credence to the trolls while also not using examples from the fringe to pigeonhole the whole.
