<human>: Can you succinctly summarize the text in 1-3 sentences?

Background: he has no job, very few friends, he spends all day inside watching TV and very rarely goes outside. He has always been very strongly opinionated and outspoken on political matters, and is in general a very negative and 'stuck in his ways' kind of person. An example is I can't remember a time he's ever told me he loved me, nor has he said anything nice about me for a very long time (years). 

His focus lately is the fact that much of my opinions are not the same as his, whereas he's really right wing, nationalistic, I'm quite accepting. Politics wouldn't be a problem if he there was anything else he would talk to me about. [If I try talking to him about anything besides politics he will flat out ignore what I'm saying or respond with a very bland answer, making the conversation unable to continue.]

Whenever I try to contribute to any of his conversations, he tells me to stop contradicting him (basically making sure I either shut up or agree). 

I normally would not give a rat's ass about this, except he's now holding things against me for disagreeing with him -- not buying school and art supplies etc. (where I live school is still on) for "being rude and contradicting him". I have no other source of money except from him, how can I deflect his responses?

   
<bot>: father is asshole. cannot avoid dealing with him. says anything disgreeing with him is rude and contradicting. how can I deflect these responses into something positive/different so I can buy the things I need?
