Conor McGregor fires back at Floyd Mayweather's racist comments 

BEFORE the reported mega-fight with lighweight king Rafael Dos Anjos, UFC featherweight champ Conor McGregor has challenged another opponent: Floyd Mayweather Jr.

In a lengthy post on his Facebook and Instagram accounts, McGregor started thanking different media outlets first for accolades and awards given to him and also added an apology for one of his Instagram posts where he was shown holding an airsoft gun that, according to The Irish Independent, got him under investigation by Irish police.

But the 27-year-old champ reserved the longest part of his message to Floyd Mayweather Jr, who loosely attributed McGregor's success to racism in an interview with FightHype.com last December as reported by Yahoo Sports' Ryan McKinnell.

"They say he talks a lot of trash and people praise him for it, but when I did it, they say I'm cocky and arrogant," said the retired boxer. "So biased! Like I said before, all I'm saying is this: I ain't racist at all, but I'm telling you racism still exists."

McGregor did not hold anything back in his response particulary directed at Mayweather:

"Floyd Mayweather, don't ever bring race into my success again. I am an Irishman. My people have been oppressed our entire existence. And still very much are. I understand the feeling of prejudice. It is a feeling that is deep in my blood.

In my family's long history of warfare there was a time where just having the name 'McGregor' was punishable by death. Do not ever put me in a bracket like this again.

If you want we can organise a fight no problem. I will give you a fair 80/20 split purse in my favour seen as your last fight bombed at every area of revenue."

Fighters Only MMA Awards, thank you for the nominations for Fighter of the Year, KO of the Year, International Fighter of the year. I will be in Las Vegas to attend the event and collect all my awards. 4. Floyd Mayweather, don't ever bring race into my success again. I am an Irishman. My people have been oppressed our entire existence. And still very much are. I understand the feeling of prejudice. It is a feeling that is deep in my blood. In my family's long history of warfare there was a time where just having the name 'McGregor' was punishable by death. Do not ever put me in a bracket like this again. If you want we can organise a fight no problem. I will give you a fair 80/20 split purse in my favour seen as your last fight bombed at every area of revenue. At 27 years of age I now hold the key to this game. The game answers to me now. 5. Media instigators/An Garda Siochana. I apologise for having the air-soft in public. I was simply rehearsing for a potential upcoming film role. I understand that the more traffic a story can get the more revenue it generates. So I understand and respect that the media must create these stories and these situations even if at times it is at other people's expense. We've all got to eat. And I eat well. So I will not complain. 6. My next fight. What can I say, it's just another night of easy work for me. I don't just own the game. I run it too.
