The random module catalogue generates random proposals for communications courses. It can propose well over a million different module titles, with well over a million billion different module outlines and details.
The modules are invented 'on the fly' by your browser linking bits of vocabulary together randomly. It is not showing you random titles from a ready-prepared list. If you are offended by any of the suggested study topics, don't blame me because I really didn't write them -- they are created 'live' inside your own computer each time you hit 'Next'.
Go back to the random module catalogue and click 'Next module' a few times.
