Isn't that just tribalism or clubism in general?

For example, if one looks at footbal (soccer for Americans) fans, their "judgement" on the validity of faults and sanctions (or lack thereof) is entirelly dependent of whose team they support and almost invariably they side with whatever the important people of "their" team (like the coach, important players and even the club's manager) say with zero logical analysis and if you actually bring logic into it and it goes against "their" team, the biggest fans just get angry and dismiss it all.

People with a strong emotinal bond to a "team" judge messages in that domain based on the messager and which team it favours, rather than on the contents of and supporting evidence for the message itself.
