Ali called Joe Frazier an Uncle Tom and a Gorilla. Social media today would have eaten him alive.
I know, but keep in mind, Frazier wasn't the nicest of guys either. On top of that, I haven't heard Ali use words that are used to insult whole groups to insult deprecate one guy. And that is just what this is, it isn't that he used the word "faggot" it is that mister Mayweather finds being gay so despicable that we are subhuman to him. And thus a terrible insult to be hurled at the other party.
In that way it is the same as if someone uses the N-Word to insult someone, it isn't the word itself that hurts the most, it is that the person that uses it thinks black people are subhuman and thus to be used as an insult.
Ali was calling out Frazier as he was taking the sides of government and white racists, something that was an even bigger problem back then than now. (And it still is a huge problem). But there are no people that are born "Uncle toms" or born "Gorillas". A gorilla is an animal, and yes that can be used as an insult to a black person, but it is nothing compared to this. Gay people are born the way they are, and to use them to question another person's abilities or credentials with a very loaded slur is extremely hostile.
Both of these idiots can go fuck themselves. And I hope nobody is even buying a ticket for that damn fight, but alas... knowing society... the "Great White Hope" folks on one side and the "Gay Bashers" on the other will by themselves flood the ticket lines over this
