Me too; as I said none of the Muslim countries are rushing to adopt it, there must be a reason.
To be honest, I think it because a large proportion of Muslims are what people here call "Munafiq" or, to use an American phrase, MINO (Muslim in Name Only). Those who oppose Sha'ria law in Muslim-majority countries are mostly I think so called "secular Muslims", so non-practising Muslims. I believe there are a lot more of those than you'd think from looking at the statistics.
