I, a non-violent person, really wish a nose-punch on anyone who uses the phrase common sense to bolster their position.

Very likely, that's because every time "common sense" is used this way, it's a logical fallacy.

Description: Asserting that your conclusion or facts are just “common sense” when, in fact, they are not. We must argue as to why we believe something is common sense if there is any doubt that the belief is not common, rather than just asserting that it is. This is a more specific version of alleged certainty.

I personally think that it also functions as a thought terminating cliche, as appeals to "common sense" seem to wind up near the end of the thread.
