Buddhists go against the idea of a God but if you have lived in a Buddhist country as I did for 5 years, they worship Buddha just like a God, only they don’t use the name God.
And that is a very good thing. You may or may not realize that what you perceive as worship may (and more than likely does) have a wide variety of meanings for different people at different times.
Using the word "god" would, at the current cultural moment, invite assumptions and expectations coming from Abrahamic traditions, which are a very ill fit indeed.
Most other traditions have a far easier time understanding that religion is about how actual people relate to their own conceptions of the Sacred. Even when they actually use god-concepts and call them gods, there is a lot more respect for the relationship between the person and the conceptions of the sacred.
Abrahamic traditions instead expect their beliefs to somehow derive from the authority of their own god-concepts and to fit other people with no concern for the actual reality of who they are and what are their conceptions of values and of the Sacred. Even people who never expressed any esthetical inclinations in the vicinity of Abrahamic god-conceptions. That is a very sad thing for everyone involved, and creates a lot of obfuscation, some of it deliberate.
