The idea of 'mickey mouse' degrees on TSR tends to be used by insecure kids doing a particular degree who are likely at the bottom of their cohort, and need something to make themselves feel better, in the absence of being able to excel amongst their peers. Attacking someone else's degree is a perfect escape for them.
I think some degrees teach more useful work skills, or more useful life skills, etc. But for practical purposes there's no reason for perceiving a difference in 'difficulty' between, say, film studies and history. Or x and y comparing many other degrees. The mark schemes are the same, the research requirement is equal, the quality of argument/discussion has to be the same. You can't write a **** essay and get a good grade in either. Too many people still have an inexplicable respect for the 'traditional' in education when, in almost every other walk of life, the 'traditional' is growing increasingly irrelevant (especially in employment situations).
