Seriously? Is this really the best reason you can come up with?
If you can’t handle Beckham’s attitude when he plays against Persija and you carry that grudge over when he’s representing Timnas Indonesia, then you might be the one being immature and problematic.
If the issue is that you find his attitude annoying during matches against Persija, why take it out on him when he’s playing for the national team?
You can criticize him, chant against him, or even be as harsh as you want, but keep it within the context of club rivalry. Don’t bring that negativity into Timnas Indonesia. People come to support the national team with pride and positivity. They don’t need that kind of energy.
And why should Beckham be expected to show respect to a specific group of supporters? Is your respect really that valuable when so many other Timnas Indonesia fans continue to support and respect him?
Lastly, please don’t drag “The Jak” into this. This feels more like a personal grudge than anything else. I believe there are many Persija Jakarta supporters who are far more open-minded than this.
