The internet is brimming with examples of bullshitters who state opinion as fact, make unwarranted declarations about their authority on a subject, and make up ridiculous rules about who has the right to enjoy or experience specific things. These people are called gatekeepers. The annoying gatekeeper is also known for putting others down for not suffering enough to warrant feeling unhappy with a shitty situation.
