Personally, I wouldn't call it "based" but him more just being a normal, balanced human being...unlike other people who can't keep their head screwed on right. Not sure how aggressively Gunnar shouts his "beliefs" into the world, as I only ever listened to "Stay Forever" and read the comments. However, DDGing his Twatter, it definitely looks like he is 100% in a certain camp. He seems like he has intelligence but unfortunately not enough, or not enough instinct to notice that he is living in a box. From what it looks like, he pretty much reads US-controlled media (like Welt, Spiegel etc) and forms his opinions from there instead of from personal experience, universal truths and reflection. Though, the "personal experience" part is always tricky with people who mostly live on the internet or in some kind of workspace bubble. The normal worker type tends to be more grounded while people more removed from that (like journalists, people doing administrative work, career politicians etc) lack some connection to reality. (Although the "some" is too often not applicable anymore today, as some have lost all contact to reality.)
And I always thought this was sad:
