Antony isnt charged
I dont understand the double standards
Voldemort isn't charged either, he is on pre-charge bail.
Double standards by whom?
The media? Not really, as there are multiple differences between the cases, not least that the UK media can't name Voldemort.
The public, neutral football fans, etc? Perhaps, I dunno. I don't follow social media other than very sporadically. There have been some reactions and calls for his club to do something (other than just keep on playing him as per normal), though of course not on the scale you'd expect when United are involved (but that isn't an actual double standard).
The clubs? As in: United have sent him on leave, let's say - whereas "North London" hasn't? Well, that isn't a double standard either, just two different clubs dealing differently with someone accused of a crime.
For the record, I have no interest in defending Arsenal here. I don't buy that they've been essentially forced to do nothing - if they cared about what sort of message it might send to just let this guy play while the investigation drags on and on, I'm sure they could have done something. The idea that they couldn't possibly drop him/send him on leave in any shape or form, because this would reveal his identity (see above), strikes me as far fetched. I could be wrong about that, but it seems odd to me that an employer should be in that position in relation to their employee.
But there are objective differences between the two cases, some of them blatant - and then you can't talk about double standards.
