But Henderson hasn't done 'A'. He's just sold out to people who do 'A'.
Whereas Gerrard has done 'B'. Which is bad regardless of whether or not he's publicly denounced it previously. Because organised crime and physically attacking people is bad by default.
That's the comparison. Gerrard's reputation is intact because barely anyone gives a shit about the moral dimension of his character. By this same measure, Henderson's will be fine also.
Your logic is astoundingly moronic. It's like saying Adam Johnson never spoke out against pumping kids so doesn't belong in the same conversation as Henderson.
The worst thing Henderson has done is that he held insincere public positions which he sold out on.
He's as much or as little of a bigot for this as Ronaldo, Kante, Firmino, et al are. Or anyone who plays for PSG or Newcastle or Man City. Which is to say, not at all.
How this is worse in your head to physically assaulting someone and being in with organised crime is just a mark of how terminally online you are.
