ad 1, possibly. So? (see next point.)
ad 2, the point is that once people started realizing that the newly formed "government" is going to abolish Russian as a language and treat the majority of the people of Crimea as if they were a small minority, the sentiments changed abruptly.
ad 3, a,b: what's your point again?
ad 3 c: Yes, see point 2. The putschist government did exactly that acting illegal and without consent of the people.
ad 4: First, it's Bandera, not banderol. Second, they came to secure their assets and were allowed to do so (i.e. perimeter around their bases and up to 20k soldiers).
ad 5: They do have bulletproof vests, sponsored by EU & US; I don't watch Ukrainian TV, I get my information from the ground; please explain, why so many military units defected. Lugansk and Donetsk are not Crimea.
ad 6: It's just pointing out the hypocrisy of the EU, US and new "government". What Russians do in their own country is their business.
ad 7: It's fine, if they did it 200+ years ago. Why do people keep forgetting that Crimea used to be a part of Russia? Seems convenient.
