Twitter has over a billion users. You can find big accounts saying all sorts of inflammatory things.
What you are complaining about is that tweets which rile you up are not censored. But those days are basically over, so you may want to consider leaving twitter if you insist on a higher level of censorship than what twitter is giving you.
Of course if you already left twitter, and are still complaining merely about the existence of a business that doesn't censor to your taste, then I would recommend looking for other past times. Try baseball.
