You're technically right about the "strongest claim," but I didn't argue about that. Whose to say that they would reinstate the Pauline Laws as a matter of fact? My argument is that claims of purest blood would likely have little bearing on any sort of outcome, and it would be wrong to require it.
Not once have I personally attacked Maria Vladimirovna in my posts, nor have I advocated on behalf of Nicholas Romanovich, who doesn't need my defense since he makes no claims to the throne.
I have said, and made my points clear. If people are of the opinion that if Russia were to recognize these claims as legitimate then Maria would just waltz into the imperial palace without causing a meltdown, they are fooling themselves and living in a fantasy. Opponents of the Romanovs and of monarchy in general aren't just going to idly sit by and let Maria Vladimirovna step in as the national savior. They will dig under every hidden corridor looking for skeletons to expose, and there are more than enough out there to feed their appetite.
You have to step back and look at the situation from that of an observer, and not someone who has publicly supported this claimant and look at things objectively.
It is estimated that around 23 to 24 million Russians lost their lives as a consequence of World War II. According to Wikipedia, between 9 and 11 million of those were military deaths and 13-15 million were civilian deaths. Both sides of the current Vladimirovich future claimant, Georgy, fought for the oppressors and opposed the allied forces. How will he or Maria expect the Russian people to handle their claim to be their sovereign?
You are however, somewhat misguided, about "initial" support concerning the 3rd Reich. Nicholas Nikolaevich hated Hitler from the beginning, and none of the Romanovs were active in their support the way Kirill and Ducky were. During the war, even Yusupov turned down Hitler's support, as did Dmitri Pavlovich, who stated "nothing would induce him to fight against fellow Russians," according to
Wikipedia.
