Anti-colonialism doesn't require moral relativism. It's as simple as that. If you want a concrete example of how signal-boosting differs from simple pushing of Western feminist opinions, the hijab debate is worth looking into. Some feminists in the hijab-wearing regions of the world see it as a tool of oppression, others not. That's a debate for them, and not for westerners to decide.
If there's a vocal contingent of Chinese women pushing for the above-mentioned patriarchal Confucian values, well... I haven't yet seen it. All the Chinese women I've yet met (and had the opportunity to speak with on the subject) view sexism as a real problem, although granted I've only ever met Chinese women who came to America so selection bias is at play.
