I know you're just posting what this guy has posted but see this poppy wanking crowd. They're up there with the most pathetic cretins on the planet.
The general feeling on it even if true, whoooo cares. It's a football kit. It's not as much of a gotcha that the guy thinks it is!
It does not matter one bit whether it has a poppy on it or not. It's not law, you do not have to wear a poppy and no one including footballers should be forced to wear one just to appease others.
If you want to wear one, cool. If you don't, cool. It doesn't matter. The narrative that someone doesn't have one on should be stoned to death is just very tiresome and needs to stop.
