Are colorblind people able to watch 3D movies with the red-green glasses?

Theoretically, yes. The lens of the glasses filters out some of the light so that one eye gets one image and the other eye gets another. If the person is red-green colorblind, that doesn't mean that red or green are invisible, just that there are wavelengths of light that they cannot distinguish. The 3D effect arises from your two eyes getting different images, not because they are processed as being different colors. This would still be the case for a colorblind individual.
