Given the task definition and input, reply with output. In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: obscene and non-obscene. A comment is obscene if it is considered offensive to the public sense of decency, for example because it too obviously relates to sex or contains language regarded as taboo in polite usage.

Comment: if you cannot understand that man cannot absolutely prove all things that are supported by science, i will not go around in circles with you. You can continue to bathe in your own ignorance. If you wish to provide an unbiased scientist who refutes the scientifically accepted theory that man is contributing more than negligibly to the progression of global warming then we can have a conversation, but it will probably be short.
Non-obscene
