Many Unanswered Questions

I get it, Travis is lonely, Travis is angry by the all the corruption and all the apathy and everything seems so pointless and everyone seems so superficial and driven by greed, and he wants to blow the whole place up.
(MAJOR SPOILERS AHEAD - DO NOT READ AHEAD IF YOU HAVE NOT SEEN MOVIE)
Why does Travis find prostitution filthy, but not a nasty porn theater? Why was he so mad at Betsy for not calling him back? He's a cabby, she works for a Senator and gave him a chance. He took her to a porn theater on their first date which disgusted her, really Travis? What was the point of that bit with Scorsese in the Taxi, seemed pointless, any man would react that way if his wife was screwing around? Why did Travis seem to enjoy the Senator but then go back to shoot him? Why did Travis think it was better for Iris to leave that filthy place and go back home to her folks, but he didn't think it was best for him to do the same, instead he lied to his parents in the card he wrote about how he's working for the govt and he cant go back to them, what great life does he have? What was with that sudden Mohawk, he only had that do for like 15minutes of the entire movie, pointless? Had many more questions throughout the movie, but can't remember them now. It was interesting, but too many contradictions, seemed like Travis was suffering from some serious mental illness (schizophrenia mixed with bipolar), don't think I have any desire to rent this movie again. Not a masterpiece to me, sorry. I usually love Scorsese and DeNiro and Cybill and Jodie and Harvey and the dad from Everybody Loves Raymond, but this was a no go.
