In Bangladesh, popular support led the government to throw away the secularism enshrined in the country's original constitution and declare Islam the state religion.

Even in "modern times" democracy and liberalism are not necessarily (or even often) co-extensive.

France would be a good western example of the frail intrinsic support for liberalism by democracy.

Why? France has been liberal and democratic for the last 100+ years.

I would say historically, particularly after the French Revolution, France had a few missteps with democracy in general, but I can see your objection.

This is why democracy is not the magical fix.

It should be noted that Turkey is generally considered a western country.

It seems to me that Turkey's politics reflect it's geography, as shown by tonight's events.

I'm confused by your comment. Plenty of western countries have coups; look at South America for example.
