You are right! Discrimination, ideologies and religions of discrimination are bad!
Hadith:
Ishaq 240 - "The Jews are a nation of liars.... The Jews are a treacherous, lying, and evil people"
Bukhari (59:727) - Allah's Apostle [said]... "Allah's curse be on the Jews and the Christians" This was spoken on Muhammad's death bed, and was one of the last things that he ever said.
Bukhari (2:28) - Women comprise the majority of Hell's occupants.
Quran:
Qur'an (9:30) - And the Jews say: Ezra is the son of Allah, and the Christians say: The Messiah is the son of Allah... Allah (Himself) fighteth against them. How perverse are they!
Qur'an (5:59-60) - This verse begets the infamous belief on the part of some Muslims that Jews are descended from swine and apes, since it says that wicked Jews (at least) were transformed by Allah in the past. (See also 2:64)
Qur'an (4:52) - Those (Christians) are they whom Allah hath cursed...
Qur'an (4:47) - O you (Jews) who have been given the Book! believe that which We have revealed, verifying what you have, before We alter faces then turn them on their backs, or curse them as We cursed the violaters of the Sabbath, and the command of Allah shall be executed.
