Since apparently this is a debate and since I do, in fact, know a couple of people who are prone to cutting people out of their lives for stupid, assholish reasons. So here’s how you can tell whether the person you are talking to has been the victim of one of these people, or is, in fact a creep:
Ask yourself these questions and it’ll become pretty clear to you that you are dealing with creep.
Pattern recognition is a life skill! The more people make a unique negative claim about a person, the more it is statistically likely to be true!
It could be that some dude’s wife is calling him an alcoholic because she’s mean and resents him having fun. His boss could be calling him an alcoholic based only on one, out of context incident. It is much less likely that both of these things are true.
Someone could be called creepy because they are conventionally unattractive or have poor social skills. But if this happens a dozen or so times in a dozen or so different social contexts, it pretty much a sure bet they are actually a creep.
