"The main problem is that there are a lot of, presumably rather unfulfilled, people just looking for things to be 'offended' by."

Unsubstantiated assumptions in this short statement:

1. A lot of people who are offended by something were actively looking for something to be offended by.
2. Those same people are rather unfulfilled (in some unspecified way, or ways).

Time to retake your philosophy module, methinks! ;-)
