Who are these parties? The Telegraph and several other respected publications?
The United Nations Human Rights investigators disagree with you:
The United Nations refugee agency has reported that more than 34,000 Ukrainians have been displaced. Most were from Crimea, where people who speak Ukrainian or do not want to change their nationality to Russian face discrimination and intimidation, Mr. Magazzeni said.
“They are mostly concerned about security: people report staying in cellars to keep away from the fighting, facing harassment at checkpoints and fearing the increasingly common abductions, threats and extortion,” the monitors reported.

So ya the Crimea has been ethnically cleansed under the illegal Russian occupation.
A) Do you not understand the concept that the Crimean Constitution clearly states that it is sovereign Ukrainian territory and their laws do not supercede that of the Kiev government or Constitution which clearly states that any territorial changes to the Ukraine can only be brought about through a NATIONAL referendum in which all Ukrainians get a vote.
B) This was not a legal cessation it was a annexation, the referendum was held through a foreign installed occupation government under a foreign occupation, it was no more legitimate than the ceding of territory from France to Nazi Germany through the Vichy government.
C) International law is not on your or the war criminals Putin's side and neither is the vast majority of the international community which voted overwhelming in the UNGA to declare the referendum illegitimate and to condemn it:
United Nations General Assembly Resolution 68/262 - Wikipedia, the free encyclopedia
D) The only reason why the UNSC did not pass this resolution is because Russia used their permanent member status to veto it, even China abstained:
UNSC Resolution on Crimea Blocked
So in your world if large hispanic heavy communities in the California, Texas, Arizona, etc voted to secede to Mexico you would call it legitimate even if they hold a bare majority? Utter rubbish this was a violation of both the Crimean and Ukrainian Constitutions, it was a violation of international law namely the prohibition of acquisition of territory through military conquest:
War of aggression - Wikipedia, the free encyclopedia
Well I'm glad you think that a referendum conducted by an occupation government under a foreign occupation for annexation into the occupying nation is legitimate; fortunately the Geneva Conventions and International Community disagrees with you, the Crimea is occupied sovereign Ukrainian territory, it is not a debate it is the law.
