I wonder if Muhammad Ali got this much hate back in the day...

Well, MA, was usually correct.
AND
He was almost always entertaining.

Is this B either one of those?

I would hope he did. I admire a lot of athletes, almost always for what they do in their sport, not outside of it. I do not admire Rapinoe at all. In fact, she killed any interest I had in soccer. And I do not understand the adulation for Ali. George Foreman? Yeah. The guy won the gold and draped himself in the flag and has never once surrendered to the PC culture. But I find nothing to admire about Ali. I'm sure he was a great fighter and he sure did like to talk a lot.

Muhammad Ali was waaaaay overrated in more ways than one, ...he was the ‘Apollo Creed’ of his time.

Foreman was all heart, while Ali was all mouth.*

Wikipedia: In an interview with George Plimpton, given shortly before his rematch with Liston, Ali expounded on the ontological teachings of Elijah Muhammad and Elijah's instructor Wallace Fard Muhammad. According to these teachings, which Ali said he believed in, there exists a space platform operated by "men who never smile" which orbits the earth at the speed of 18,000 miles per hour. The platform contains bombs which would be dropped at Armageddon which would begin after a threshold in the earth's collective guilt had been breached. Ali claimed he had seen the platform on several occasions. A member of Ali's entourage, Cody Jones, who was also present during this interview, corroborated what Ali said and claimed he had seen the platform together with Ali at five A.M. one morning when the two were out jogging. Jones described the platform as "a bright light darting in the sky." According to Plimpton the "bright light darting in the sky", seen by Ali and Jones, was probably either Venus or Jupiter.

He knocked people out, she got knocked out.

He didn't hate his country, disrespect the anthem while representing the country and call for men to be allowed on girl's teams.
She is awful.

Why are people responding legitimately to your obvious stupid bait post? Your responses here prove it.

Comparing a great like Muhamned Ali who received hate from toxic hateful racists to Rapinoe who is a toxic hateful racist that gives out hate. No doubt if you'd lived in Ali's time or he was still around and being outspoken, you'd be the first one that would've called him the N word constantly because you leftists think you have that pass and hate when a POC doesn't agree with your delusional ramblings and I bet Ali would've said there are only 2 genders and that would've sent you Liberals intro a frenzy.
