Which England players were singing it? I've never seen it but maybe they did
Two wrongs don't make a right though.
Besides, if English players today were singing on a live stream, I'm sure they'd be called out over it.
No one is talking about "making a right". You'd be a lot less confused if you actually read the comments you replied to (and the comments they were replying to).
I was replying to someone who declared singing offensive songs about the opposition was a new generation thing, and I responded by pointing out there's been dozens of these songs for decades and the only difference is it gets recorded and goes viral now.
