to me, the issue is not whether china should eradicate islam - they clearly should, along with all other systems of superstition and backwardsness.
the issue is urging them to find humane ways to help people choose to leave the past behind, rather than force them to with violence.
and, a word of caution is required - eradicating superstition by force is never successful. look at the power of the church in russia, today. people need to be convinced to leave religion behind, not forced to stop engaging in mindless rituals.
