Video showed Souleymane Sylla being pushed off the train by Chelsea supporters, who were singing "we're racist, we're racist and that's the way we like it".
Sylla said: "That's things we used to see in films actually. I used to hear the story of Rosa Parks," the American civil rights pioneer arrested in 1955 for refusing to give her bus seat to a white passenger.
"But I didn't believe it would happen to me", Sylla told FranceInfo radio.
During the trial, Parsons issued an apology, but despite the damning footage, he denied there was any racist aspect to the incident. "I am very sorry to Mr Sylla, but I was not racist in any way," he said, looking Sylla in the eye.
He admitted to preventing him from entering the carriage but claimed the racist chants had come from another carriage.
Under French law, the four faced maximum jail terms of up to seven years and a €100,000 fine on charges of "voluntary violence aggravated due to its racist nature".
Sylla said: "I haven't forgiven them and won't forgive them". He said he had struggled to recover from the traumatic incident.
The judge ordered the four men to pay €10,000 in collective compensation to Sylla, and €500 individually.
