I do agree that Muslim has largely forgot what the Message of Islam is.
But Muslim is not a label that you carry.
Show me a believer and I’ll show you he give other’s their rights, do salah, pays Zakat etc.
But not ever person who call themseves Muslims, do Salah or pays zakat is a Muslim (you don’t have to go very far reading the Quran, to find out that). Quram mentions the way these people get misleaded.
