Did you even read my post? I was clearly talking about Russian citizens (as in, people who had travelled from Russia), not Crimeans (who are still considered Ukrainian).
Stop talking about this in such definitive terms, it just makes your point look ridiculous. On just the last page a 2012 poll was mentioned where 71% of the Crimean population wanted to stay as part of Ukraine and while I'm sure that's changed since then, it's clear evidence that this issue can't just be determined based on ethnicity alone.
Also, let's say you were right, you'd still only have a 58% chance of someone telling you they're "Russian." That's a majority but not a vast majority. Certainly not enough to decide something as important as breaking away from their country (without a Russian gun pointed at the head anyway).
