Is it funny?

A blog post on Huffington suggested that some topics are just not funny for some people. 

They're right, some are not.

If someone laughs, does that mean it's ok to have shared the joke; on the assumption that generating a laugh was the intention of the joke in the first place?

Who is the barometer of comedic value? Someone who's offended, or anyone that finds it funny?
