We've Said No To Racial Hatred; Why Not Say No To "Kafir" Hatred?
"Kafir" is a derogatory term for infidels -- that is, non-Muslims.

Bill Warner explains that just as we've said no to racial hatred, we need to say no to ugly Islamic dictates:

We need to say no to Sharia wife-beating, no to Sharia Kafir hatred, no to the Sharia killing of apostates, no to Sharia suppression of free speech, no to Sharia abuse of women.

Unfortunately, these are all part of Islam.

Take wife-beating -- "Wife Beating- Good Enough for Muhammad, Good Enough for You":

Look, we're all in favor of Muslims bringing their religion out of the 7th century, but if this can only be done through strategic omission and fringe sophistry, then we have to ask what is the point of salvaging Islam? Why not just pick another religion that's closer to what you want Islam to be?

Is it because the Religion of Peace threatens to kill anyone who leaves?

Never has this means of intimidation been more necessary than in the information age, when many Muslims are learning for the first time about the history and true teachings of their religion, and how poorly it contrasts with others.

P.S. The multilingual site, IslamQA.com is quite blunt about the four conditions under which a husband may beat his wife

Discipline. The husband has the right to discipline his wife if she disobeys him in something good, not if she disobeys him in something sinful, because Allaah has enjoined disciplining women by forsaking them in bed and by hitting them, when they do not obey.

The Hanafis mentioned four situations in which a husband is permitted to discipline his wife by hitting her. These are: not adorning herself when he wants her to; not responding when he calls her to bed and she is taahirah (pure, i.e., not menstruating); not praying; and going out of the house without his permission.
