Hypothetical Gay Marriage Referendums round world?

[Santander]

The Netherlands probably would vote 90-10 in favour (if non-SGP voters would even bother to turn out). The 10% would be an interesting coalition of SGP voters, the majority of CU voters, a lot of DENK voters, the few hold-outs in the CDA (lol) and some diehard homophobes in the PVV. And even then 10% is generous.

I have a hard time believing any country, even the Netherlands, would support SSM 90-10 with secret ballots in a legitimate referendum.

Yes, of course I agree that a referendum wouldn't be close. As you said, the exact numbers would depend on the turnout.
