It's definitely not personal. He is just extremely arrogant and plays for Franco's team. Those things in combination with each other are disgusting.
The "Franco's team" meme is, at best, pretty questionable, and has been mostly disproved over the years.
I recommend Sid Lowe's "Fear and Loathing in La Liga" if you cannot be bothered to read more political books.
It also contains fantastic material on the Di Stefano saga, Real becoming a powerhose with him, Paco Gento, Kopa, Puskas, etc..., Barca's teams with Kubala, Herrera going to Inter to re-invent football, Cruyff's team, Quinta del Buitre in the 1980s, Cruyff's return as manager and the final jump of Barca from "goodness" to "greatness", Galacticos, Messi, etc... All the way to (IIRC) 2014 season.
(it's a fantastic book, one of the best football book I've ever read, and you won't be sorry if you give it a shot)
In short, Franco's "team" was Atletico Madrid (renamed to Aviancion after the Civil War).
Franco "embraced" Real Madrid only once they became a European success and proven winners... He used them for political gains and show and propaganda... A Castillan team winning ECs was perfect for him to show "unified Spain" etc.
From the end of the Civil War to 1952 Real Madrid won exactly 0 (zero) La Liga titles and Franco showed no interest in them (the possible exception being the 1948 Cup Final vs Barcelona, but by all account that had more to do with a Castillan club playing a Catalan club than Real specifically).
Atletico won 4 tittles, Barca and Valencia 3 each, etc. Zero titles in 15 years doesn't sound like a regime club in a fascist state, does it...?
It started changing once Bernabeu build the stadium, got the core of his team set and brought in Di Stefano and then Kopa, Puskas, etc.- and become multiple European champions. And only then did Franco become a "regular" at Real's big home games.
Don't get me wrong, there was shady stuff in the Kubala and Di Stefano transfers (Barca getting Kubala, Real getting Di Stefano eventually), but we do know that neither was decided by Franco, not even remotely close. Bernabeu did use his influence in the Di Stefano transfer (after they felt they were robbed of Kubala, and Bernabeu even got Kubala's family to safety) but it was a mess between the government, three different FAs and four different clubs.
Anyway, again, I recommned Sid Lowe's book.
