Didn't seem very fascist when I was there. The Economist Intelligence Unit has it as a 'flawed democracy', the same category as the US. (https://en.wikipedia.org/wiki/Democracy_Index)

The Democracy Index rankings are non-transparent measures by a less than objective organization that places significant weight on a country's openness to multinational corporations.

Singapore specifically is an example people use to illustrate the inherent flaws of the Democracy Index rating system. This is a country with low press freedom, one ruling party that sues the opposition into bankruptcy for "defamation" to prevent any loss of power, and oh, they execute people for carrying drugs.

The extent to which their political and economic system is influenced by fascism may be up for debate, but given that they've not conducted any genocide or imperialism, the charge doesn't hold the gravity that you intend.
