Aside from the issues mentioned in the OP?
Or if you are gay? http://en.wikipedia.org/wiki/Section_377A_of_the_Penal_Code_...
Or immigration policy? http://www.bbc.co.uk/news/world-asia-21485729
Or...
I live in Singapore too, and while there are plenty of pluses there are also plenty of minuses and they shouldn't be minimized or ignored.
It is, after all, the league that Singapore wants to play in both in image and influence.
Section 377A is pretty rarely (if ever) enforced nowadays, and judging by the government's current lacklustre response to protests against it, I have a feeling they'll probably be repealing it in the next couple of years.
There's even a gay village up in Changi.

The government has reacted to that by tightening up visa requirements. Probably not nearly as much as the protestors, but they're still paying attention and responding.
Not saying that these aren't issues, or that they shouldn't be protested, but compared to most other countries, you've still got it pretty good here.
However I will not go as to say Singapore is less democratic due to this point.
(As an aside, it is crazy how many Americans seem to have crazy xenophobic attitudes, too. On their `left' and `right' of the political spectrum.)
