blasphemy and Buddhism

.
Posted elsewhere, but I thought I would put it here too:

As far as I know, "blasphemy" entails speaking or acting wrongly in regard to some deity or belief system. Hence, in order to blaspheme, there must first be such a deity or belief system and thus any blaspheming must posit or elevate that which it opposes.

I do not believe blasphemy is possible in Buddhism since, in practice, there is simply no footing for deities or belief systems.
