The problem is any fanbase would be pretty much the same no matter how much you want to believe otherwise that your club or fanbase is 'special' or more morally upstanding. You can only deal with individuals one at a time rather than criticising a full fanbase for it. Social media and the horrid football "banter pages" and shit Paddy Power memes have created an environment where your team having the bragging rights just right now is more important than acknowledging that the reasons they have them are a bit dodgy. I'd deem Everton to be a football club with a fanbase that have genuine morals and wouldn't just roll over to have their tummies tickled if the club was bought by a dictator or something, but Alisher Usmanov, a known dodgy bastard and Putin affiliate, was involved with us in the background for a while until he was sanctioned and there was no shortage of Evertonians on Twitter calling for him to sponsor the new stadium or whatever to cause a Man City-esque cash injection to the club that subverted FFP.
And that's another problem in itself, as soon as one club does what City have done with their financial "peculiarities", got away with it and been rewarded with trebles and domination of the English game, why should any other fanbase feel bad about doing the same thing? It just gives any fan such an easy excuse to say 'well our club might be doing this but look over there'.
You might like to think Liverpool fans would be different and you'd hound out any Saudi or Emirati owners but as soon as they bought you Mbappe or something you'd get enough people on social media saying "it's not ideal but this is what we need to stay competitive" and "I don't care what happens off the pitch, I just support this football team" and "City and Newcastle have done this so why should we feel bad about it" and then you all get tarred with the same brush of defending the corrupt owners or regime.
I don't know many Newcastle fans so I can't judge what sort of proportion of their fanbase is doing these mental gymnastics to convince themselves and others that the Saudis aren't as unpleasant as they are. Some people put a lot of effort into it though and anyone incapable of condemning them should be challenged on an individual basis.
