Because he thinks he eats too many McHamburgers,
And he thinks that porn is the best piece of ass hes ever going to get
And he thinks that his hat isnt quite perfect enough
And he thinks he's too short
And he thinks he's too small
And he thinks he's no fun
And he thinks his heart is black
And his bank account is always two steps behind
And his home is a hole in the ground
And he thinks his skills have a limit
And his prospects are blind and too selfish to treat him fairly
And he thinks his past is too tainted
And his family is too ignorant
And he thinks that he's too weak to break free from any of it even though he knows that it's all fucking bullshit.
Tom hates himself because he relies on the excuse and habit of hating himself as a reason to wallow and not push his limits and not risk loving and not really live.
Tom hates himself because he knows better than to hate himself, he knows that he loves, and he knows that what he loves is what he is. Its inevitable. Its human nature.
Thereby the concept of self hatred is flawed and impossible... an oxy moron of hating to love while loving to hate
... a trick to the mind to distract from the heart the inevitably infinite and all encompassing existence and continuum of love.
