Most in the west who've visited Singapore are quite impressed by it, those who haven't but have heard of it, perceive it as a strict place (thanks to Michael Fay). Reports of Sg in western media describe it as a functional place where things work. And some (Goad forbid) make hints of emulating Peesai.
I lived in Singapore upto the early nineties. Compared to liberal industrialized democracies, it was strict. And idiotic - the authorities BANNED full-face helmets and for awhile, evrey motorbike more than 175 cc had to install "crash bars"); the entire motorcycle industry worldwide called these engine guards, only the ST called them crash bars. Long hair was frowned upon, pop/rock show were mostly censored, and if allowed, under controlled conditions. My mother and aunts went through the stop at two stage - but it wasn't forced down their throats, they could've not opted for sterilization if they didn't want to. Graduate couples? He suggested, but there wasn't a fine for not following. Despite all these, Singaporeans enjoyed freedom to vote, form political parties, travel to most places on the planet, practice their religion/cultural rituals and celebrations. This is not a sign of an oppressive state.
The only thing the idiots in Sg did cock-up on was repeatedly vote the same cock-heads again. What can I say??
BTW, although I disagree with LKY, I wouldn't place him in the same boat as the other two you mentioned. LKY gets invited to top Unis the world over and get given medals (I wouldn't give it to him though), I doubt if these organizations will bestow the same to these other tyrants.
I am not Singaporean, I don't need to know the itty-bitty details of the island city-state, just enough to get by will suffice.
Cheers!
