It's a fact not a comparison. They are in the ring in s brutal sport where their opponent can be killed and they are illegally enhancing their strength. That is pure scum.
Jon hit a pregnant woman while driving under the influence and ran from the scene. That's 10 times worse then what mcgregor has done outside the octagon. Yet he got special ufc treatment. Hopefully you now see the light and understand mcgregor isn't the only one. If you were a hard-core fan for years like myself you'd already know this.
what jon jones did was messed up, but it had nothing to do with the UFC, what conor did has everything to do with UFC, he attacked a bus full of ufc fighters. steroids is basically cheating, but ufc fighters can easily kill somone with out the steroids.
