Hmm, you said..
"Oh yeah! I forgot to mention that the archenemy is way more successful and way more popular than I am at comics"

Would that make Britney Spears a better musician than Amadeus Mozart? Britney Spears is way more successful and popular at music than Mozart was. Mozart was considered a 'freak' in his time, died penniless in a pauper's grave, and wasn't acknowledged until after his death. I think that Mozart probably had many enemies when he was alive. Think of Van Gogh. He barely sold a painting while he was alive, considering himself a failure compared to the throngs of anonymous 'Salon' painters of the day who painted bland, carbon-copy nudes and landscapes for patrons.

You speak about having a 'defective' personality. I think (and I might be going out on a limb here) that most artists and creative people feel this way about themselves. This is what spurs them to become artists to begin with, and not Politicians. It starts the whole process of introspection. "There is something 'wierd' with me. I have to find out what it is." Then you express this 'wierdness' in your art. This is what makes it unique. This expression of the unique perspective gained from your 'defectiveness' is what separates art from illustration.

Oh yeah! Jay is right. This guy sounds like he is ego-tripping on you, possibly due to the pressure of the 'friends' of his that were dissing you. If he has to ban you from his house to stop you from expressing your opinion, it's probably because he felt threatened by it. Otherwise, he could just politely point out what he disagreed with about what you had expressed.

Banishing you from the land of Naquadah for expressing an opinion he didn't like? Who is this guy, Stalin? Doesn't this guy beleive in freedom of speech? Does everything have to be cleared with the politbureau before this guy will accept it? Maybe he is starting his own politbureau. As a creative person and an artist, you are way better off avoiding these people.

He kicked you out, because you expressed an opinion that he didn't like? That's called 'Argumentam ad Ignoratium', one of the classical fallacies in argument. It amounts to saying
"I don't acknowlege what you say, so I win." Kind of like a five-year old plugging their ears and stamping and saying 'Na-na-na-na-na! I can't hear you!"

Are you afraid of this guy beating you up? Are you afraid of the social censure because he is in the same social circles as you? I would like to suggest that you could turn the tables on this guy by taking the whole event and turning it into a comic book, sort of like Harvey Pekar "American Splendour" style. What you are going through right now is something that everyone has experienced before at some point in their lives, and it's something everyone can relate to. You'll get your chance to express your opinion to everyone as a whole, while subtley showing those in the know what a creep he is. Best of all, he and the others who dissed you will know that you are talking about them, but they will never, ever, ever be able to tell anyone about it ever! Just make sure that you make the characters in your comic anonymous by making them rabbits, or robots, or even just people with different names. Stay true to the story though.

These people that dissed you will probably not even hate you for it, they might feel ashamed for the way they treated you. Even if they did want to pound you for it, there is no way that they could do it without revealing that it was them you were lampooning in the comics. If you were really afraid, you could do it under a pseudonym and claim it 'wasn't you'.

The good thing about making a comic about it is that it is a real life story that is ready made (you don't have to come up with a plot, characters, etc...). Also, it is a good way to work out your anxieties about the situation while resolving it at the same time.
