We can cherrypick examples from both sides.
There are also lot of anime that take an anti-reactionary turn, like One Piece, TTGL, KLK, Gatchaman Crowds, the whole Gundam series, GitS SAC (especially 2nd), Outbreak Company, Code Geass, Sora no Woto, most stuff by Ghibli and Bones, hell even kiddy shit like Precure or Conan (there's a whole discussion about it here http://fox.2ch.net/test/read.cgi/poverty/1444656879/ ).
There are also works that get interpreted as reactionary while the author is actually trying to criticize it by overexposing it. For example Jin-Roh is often cited by /pol/ as a pro-nazi anime but the creator, Oshii Mamoru, literally participated in radical leftist protests in the 60-70s. There's no way he's idolizing nazis. Same as Asobi ni Iku yo; it was mentioned due to this scene with cat nazi aliens but the author (Okina Kamino) is a traditional leftist (he seems to be strongly anti-imperialist, being from Okinawa).
Of course there's a relatively high amount of reactionary works written by genuinely reactionary authors like GATE, Joshiraku, Mahouka or Kamichu, but as I see it they're mostly isolated, although they seem to be increasing lately.
My point is, that the amount of them doesn't seem high enough to explain alone the pressingly high amount of reactionary otaku.
