I don't enjoy something less because some people enjoy it more than I do, no. Of course, if I think that something is overrated, then by definition I won't like it as much as most others do.
Fortunately, outside of that one thread, Dr Aum speaks with the same voice as Mr. MILF.
Edit: That said, I'm not at all averse to pretending to dislike things, or exaggerating my opinions on them, in order to wind other people up.
