Do you Greet nonmuslims on their festivals?

Re: Do you Greet nonmuslims on their festivals?

*Mushrikeen *i.e. those who commit *shirk *(sin) by indulging in idol worship or polytheism ? But a *mushrikeen *can also be a kafir and vice versa.

Irrespective of what they are called, can you show me where Islam teaches Muslims to accept and respect them ?
