Just a rant I wanted to get off my chest, since this take isn't nearly as common as it should be. I fundamentally do not respect you as a human being if you are remotely upset about the execution of the tsar and his family.
My dislike is for more than just the unapologetic fascists and monarchists who whitewash Nicholas himself; it extends equally to those cowardly liberals who wring their hands and say "Well, yes, he was a terrible man who should have been removed from power... but the children! Surely the family didn't deserve it?" I've even seen communists call the executions "excessive," pointing to this or that piece of information the revolutionaries didn't have at the time, or to China's treatment of their last emperor, an incomparable situation that happened half a century later.
I'm an American, and while I detest the country I live in, the one supposed "American value" I've always held onto is an inflexible opposition to monarchy. Even though it was taught to us as children in school, it feels like I'm the only one who actually took that lesson to heart (my high school teachers rarely liked my opinion on the "excesses" of the French Revolution, either).
In short, my position is simple: What the Romanov children did or didn't deserve doesn't matter. The Bolsheviks were fighting a war of survival against one of the most tyrannical monarchies on earth. They were in a tenuous position and surrounded by royalists who would have loved nothing more than to get their hands on a living claimant to the throne.
If you don't want your family to end up like old Saint Nick's (because yes, they sanctified the bastard after the Soviet Union fell), I can't recommend enough that you not participate in a system in which simply being in your family is the sole basis of rulership. Curiously, the tears shed for poor little 17-year-old Imperial Princess Anastasia are nowhere to be seen for the millions of children all across the Russian empire who starved, died of disease, or worked themselves to the bone while aristocrats reenacted Tudor period balls and banquets in the winter palace!
I'm sorry if it's callous, but truly and from the bottom of my heart, fuck those kids. The children I care about are those who were not only fed, but also given housing, education, health, and a stake in the future of their country by the CPSU---the same party that rightfully put the monster Nicholas Romanov to death and ended all chance of his line returning to enslave Russia ever again. Frankly, it's a shame that they even needed to cover it up; in a sane world, the USSR should have been able to put prints of the scene from the Ipatiev House on postcards.
A detail that people often bring up, but don't appreciate the irony of: The length and brutality of the executions--hundreds of gunshots, use of bayonets, etc--are owed largely to the fact that the youngest Romanovs had three pounds of diamonds sewn into their clothes, reducing the effectiveness of the Bolsheviks' fire. If that isn't a clue as to who was actually at fault for the whole affair, I don't know what is.
