The basic idea of this article can be seen in its title. The author is criticizing Malaysia’s politics for two reasons. First, he says that Malaysian politics is dirty. Second, he says that it is vulgar, by which he means that it does not focus on the things that are truly important.
The first half of this opinion piece is dedicated to the idea that Malaysian politics is dirty. By this, the author means that various groups tend to resort to dirty tactics in order to win elections. He mentions, for example, two instances in which sex tapes purporting to show political candidates have been leaked to the public. He also attributes the recent incursion by Filipino militants into Sabah state on Borneo to political maneuverings.
The second half of the piece argues that Malaysian politics is not focused on the issues that are most important. The author argues that populist policies tend to pander to the public without solving problems. He says that the government focuses on silly symbolic things like trying to get theaters to play the national anthem before movies instead of trying to solve Malaysia’s real problems.
Thus, the author argues that politics in Malaysia is both dirty and vulgar.
