This is what makes me think it's a bit - Sander Schimmelpenninck is a Dutch op ed writer who likes to pretend to be a lefty but always rallies for the centre right party, and he grew up in a castle

And "Rutger-Jan" is a very posh name. Like comically so.

So that name going "yeah I'm a gonzaloist" just has to be a bit. Also isn't that Pol Pot in his banner image?
