There are about 100 referenda listed here. It is a normal process of decision making whenever a group of people want to unite to become a state or disunite to dissolve a state. Civil wars are exceptions, not the rule.

Your first response was relevant, and I recognised it, this one is just silly. Please spend more then a few seconds thinking about the issue before replying needlessly, and wasting time.
The issue is specifically about a referendum in an independent country, for one region to be given the right to full independence, without a bloodbath, without physical fighting.
This is not the norm, nowhere near the norm, it simply does not happen, except on rare occasions.
Did you even read before you sent me those links?
Those refer to referendums post Soviet period, or post Yugoslavia period, or post colonial period. So in situations where the exiting nation state was already defunct, or in a process of the ending of colonial rule, that's a totally different condition.
Plus, many of those are in some tiny countries that don't exactly have the same strong governing structures as large countries.
Plus, many of those referendums took place post civil wars or wars of independence. Or, civil wars started after those referendums, so no, they do not apply to this situation.
Algerian referendum was organised after an 8 years long war of independence in which over 1 million Algerians were murdered by the French.
Catalan referendum, in a European country was declared illegal, and the leadership had to go into exile for safety.
The same applies to other examples in those links. Please stop wasting my time, you should have stopped after the first reply. Which if you read my reply, I had appreciated.
