Noel is angry about every single thing about Liam and even said he hopes Liam is having the shittiest time of his life. Liam has never got down to such a low level like a kid, has never hoped anything could go wrong both in Noel's music and life.
Low level like Noel's new album...
If you don't care about someone, you shouldn't be so bothered. We never said we're not interested in Noel's music, but now he's dropped both musically and as a person.
These people are used to insult each other, also as a joke, a banter, that's how Oasis worked. But Noel has a different tone with his insults (also insulting Oasis' fans who made him rich... classic Noel hating the fans, even his own fans). He's childish (just like when he wished to catch Aids and die, at Oasis-Blur times).
Noel sounds like a pacifist who says to love everyone and then he doesn't tolerate even anyone who has a different opinion.
What's Noel's final purpose? going on like this, he can have a fight with Oasis' fans. Without bodyguards, he would surely ran away like the scaredy cat he is... the hero on the media only.
Let's see if he repeats all he says also in front of us, so he can check if "we have no life", "we are 15 years old", etc. Old fart.
In everything Noel says there's something clearly wrong, so it seems like truth offended him.

And... look who's talking : Noel about writing songs and Liam paying, that Noel is still paying royalties every time every CD is sold, for all the songs he copied.
It's clear that "team Liam" hit the target and Noel is angry about that.
Thank you Noel for showing us how we should NOT be in life.
