Haven't read anywhere how it started but by the looks of the video, the aggressor is the fella with the bottle, he swings it at Stokes mate then Stokes just loses it and piles in, imo.
Yeah, can see him swing a bottle and then gets a kickin. "Apparently" he was defending a homophobic attack.
Fair play, even if it is just for giving the twats who swing bottles a kickin. The one who drops is the one who swung the bottle.
In that situation it's hard to say how you would react, if somebody is going to use a bottle you are going to make sure they aren't getting up.
Press going mad about 15 punches in a minute, it's not really that many.
