Tourism industry operators were scheduled to hold a rally today to demand that the government address the declining number of Chinese tourists. If they are only concerned with their own selfish interests rather than the public interest, or if the protest deteriorates into a standoff between the pan-blue and the pan-green camps, it would lose much of its legitimacy. It would then be a repetition of last week’s disastrous demonstration by civil servants, public-school teachers and military personnel; a venting of anger that would not receive wide public support.
