What characteristics make a man a creep?

Someone who goes out of their way to pay inappropriate attention to people they have no business going to..

When they leer and lurk

Some things that have creeped me out from men over the years:

Staring at me for longer then a minute. Women who do this creep me out too.

Trying to follow me home or make excuses to try and come inside where I live when I don't know them. Or following me when I'm out on a walk or going somewhere and watching me.

Or watching me from a distance for several days when I go out to a track to run.

Acting like a d-bag and treating other people crudely or callously or with cruelty.

Unusual, gross, or illegal sexual obsessions creep me out.

A man telling me about the illegal pervy things he's done to harass other women or other people.

Telling me that he'll stalk me, or do inappropriate things to me.

Spying on me or other people changing clothing.

sending creepy messages or pictures.

Follow me and tries to insist on doing something nice for me when I don't know him.

A group of men following me and chatting me up about how much they think I'd like their dicks and then grabbing my arm to get me to stay longer then a short polite conversation.

I could go on and on...

In general the men I stay away from are any men who would treat me totally differently (like a object with no right to say No) if I'm by myself verses with my partner or with a male friend.

Not understanding no and having no social skills, regardless of if they are innocuous.

Registered sex offender, the guy who isn't allowed near children. A guy who doesn't get that no means no.

According to a lot of people I come across it's the Y chromosome.
