'Punch him in the crotch'

Hating people just seems to come easily to me. I have never been one of those people who will happily strike up a conversation with whatever stranger stands next to me at the bar. I would happily have 'Fuck off' tattooed across my forehead if I wasn't so worried it would be a conversation starter.
There are many people around me who are the type of people to start a conversation with someone who has 'fuck off' tattooed across their forehead. There's my mother who thinks that every booze hound is a fellow friend, and there's my friend who spent a drunken evening giving a homeless guy her phone number. Unlike my mother I would avoid the booze hound for fear he would touch me with his sticky booze hands, and render me over the limit with his breath. The only conversation I would ever have with a homeless person is why they always seem to have a dog? Where do these dogs come from? Considering the dogs condition how have they been able to feed the dog with no money?
This may be a huge factor in why I am still single. I don't want to talk to people. They might not be interesting and worse than that, they might touch me. I'm very happy to hug friends and family, they've stuck with me for years and it's one of the few free ways you can show affection. I do not hug people I have just met. A guy once introduced himself to me with a very gallant kiss on the hand, in my haste to move my hand away I slapped him in the face. These are things that I can probably work on seeing as I have such total self awareness. However as previously stated my complete stubbornness prevents me from making any true changes to my personality.
One thing that will never change is my ability to immediately hate people. This probably would have changed by now if they didn't keep proving me right!
My hatred for certain people is starting to cause serious worry. Either because A) I'm going to start acting on my day dreams,or  B) I'm going to be investigated for sexual harassment.
This guy has never done anything to me personally but I hate him. He has the unfortunate gene that portrays itself as a face that inspires everyone to want to punch it. This gene was no doubt an evolutionary attempt at anger therapy. Cave men were a lot less likely to go on a killing spree if there was just one particular face they could pound on guilt free.
Everything he says sounds condescending and like all annoying work folk he's a kiss ass. He has his tongue so far up our area heads ass he can probably taste the chip fat he uses as hair oil. To get through the day I've been doing 1 of 2 things, which as previously mentioned may get me into trouble. The first is Dexter themed day dreams where I consider each of the office items and calculate the ones I could kill him with and make it look like an accident. I've got up to 5, including a hole punch and a paper clip.
The other reaction is a little voice that screams at me every time he speaks. Whenever he starts a sentence the little screaming voice says 'PUNCH HIM IN THE CROTCH'. Staring at your colleagues crotch is grounds for disciplinary. Explaining that you were just imagining punching it is grounds for dismissal.
