With scathing words like these, it's sure to attract big attention:
1) "I'm not a man who picks and chooses his fights out of fear."
2) "You ruined your legacy to a certain degree because you didn't have the balls to fight Manny for years."
3) "Excuse after excuse is what the fans kept hearing from you, and now [you're] angry [you're] not loved?"
4) "Who was the man you fought after Manny? I don't think a lot of people out there know because it was one of the worst pay-per-view ratings of all time."
5) "Enjoy yourself buddy yeah...ya little bitch."
But here's the catch: The post did not come from Conor McGregor's official page. This is Conor's official page (https://www.facebook.com/thenotoriousmma):
This is the page from which the post came (https://www.facebook.com/weird.pawn):
As to why the McGregor fan page went on this social media attack? It wasn't unprovoked.
Back on December 30, 2015, Fighthype.com published an interview with Floyd where he said:
"And what’s so crazy, I don’t really know the McGregor guy; never seen him fight. They say he talk a lot of trash and people praise him for it, but when I did it, they say I’m cocky and arrogant. 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."
These were the lines that stirred the hornet's nest. Still on the issue of race, Mayweather also stated that Ronda Rousey only became so famous so fast because she was white. He asserted that the boxer Laila Ali, who retired undefeated, was equally dominant but didn't get quite the commercial success as Rousey because Laila is black.
The statements incited the fan page's response, about which the website Uproxx.com had this to say: "If Mayweather wanted more McGregor-style accolades, he should have gone out and fought like McGregor."
Non-fact: That the real Conor McGregor posted the message on Floyd's wall. The McGregor fan page cleverly only made it seem like so. (Or if this is really from Conor, we hope he owns up to it soon.)
