If it is your fear that government would something to you if you voted for the opposition, then you should appreciate what oppositions like Chiam, Low, Sylvia....are going through. Our support to them would be to vote for them without fear.
I voted for WP in Aljunied and am waiting for an opportunity to be asked by a government ppl, "why did you vote for the opposition?"
My understanding of the term "Voting is secrecy" is that you respect how others voted and do not ask them who they voted for, but my preference for the political party is not a secret and I am always ready to make it known.
If you voted for the opposition but afraid of the repercussion, so you started saying good things about PAP, that you are truly a hypocrite.

you are no better than the cowards who voted for PAP out of fear, but I thank you for your vote for opposition, every vote counts.
