Yet Myanmar ,

Myanmar wasn't a democracy.

Thailand ,

This prime minister was removed by the court, not by violence.

Nepal , and

This is the only example you gave of a democratically elected official who was violently overthrown. I said that if you violently overthrow a democratically elected tyrant, the majority will simply democratically install a new tyrant. That's exactly what happened in Bangladesh, with the same party being elected after it was violently removed. Nepal seems to be a vanishingly a rare counterexample. We'll see how long that lasts.

Spain uprooted their oppressors violently without democracy.

Spain also wasn't a democracy.

South Korea kept it's democracy by taking the tyrant violently .

Also removed by the court, not by rebel violence.

It just seems the disconnect is plain old complacency.

No, if you violently remove a democratically elected official, that official will be democratically replaced with more of the same. Violence doesn't magically change voters' minds to agree with you.
