Should people attend the protest in Hong Lim Park against the proposed increase in GST?

I asked this question in The Wisdom of the Crowd - Should people attend the protest in Hong Lim Park against the proposed increase in GST?

Here are the votes:

We must make our voices heard even if the government does not care to listen - 52%
We must tell the government that GST should be reduced or abolished - 30%
We should keep GST at the current level - 11%
We must increase GST to allow the government to spend more on social benefits - 7%.

82% are against the proposed increase in GST. 18% support it.
