Muslims praying in a relief society room with images of Christ covered

[Niblo]

People here may disagree with the beliefs of some or all Christians, or even mock those beliefs, but that's not the same as getting the beliefs wrong. The problem with ceeboo's statement about Muslims worshipping Muhammad was never that the statement was offensive to Muslims. The problem with the statement is that it is wrong. Whatever else Muslims do or don't do, they do not worship Muhammad.

Perhaps Niblo or any other Muslim can correct me if I am wrong, but my impression is that Islam is more about only worshipping God than it is about anything else. So regardless of how offensive it may or may not be, to say that Muslims worship Muhammad, I think it's a pretty big and basic mistake about Islam.

Yes.

It is indeed incorrect to state that Muslims worship Muhammad (peace and blessings be upon him). To repeat: Muslims worship only Allāh (subḥānahu ūta'āla).
