No, most of them don't keep quite. I know many feminists who protest against sex-selection as a justification for an abortion even though they protect a woman's right to choose to terminate their pregnancies. They hope to persuade women not to follow that practice without recommending that the gov't not use the force of law to forbid some women from getting an abortion. It's similar to American gun control opponents who detest those who use guns to commit crimes while protesting government involvement in forbidding such people from owning guns. In both cases, they want people to behave better without trusting the government to get involved without becoming heavy-handed in their role. Perhaps the feminists you're acquainted with don't tell you that sex-selection bothers them because they're afraid you'll advocate that all abortions be banned as the best solution.
