I may not have the chance to ask him personally, but I should expect that Putin and I would very much agree on a large number of questions, including: "is it, generally speaking, preferable to find oneself on the presence of breathable, oxygenated air?", "do you personally positively enjoy being kicked in the shin?", "given the choice between a multi-million lottery win and bankruptcy: which one would you pick?", and "would you tend to agree that the sky is typically not depicted as being yellow in crude drawings?".
For all I know, Putin and I might even share the same taste in food, music, art and entertainment (well, maybe not the latter: I do ride horses, but I've yet to try it while going topless).
Surely, none of this has any bearing on his general moral character or stance on specific questions.
This has got to be the fallacy of ... whatever the polar opposite of "ad hominem" is. (Best guess, without having researched it any further: argument from authority?). And it has the devastating effect of minimising the indefensible by highlighting the "positive" aspects.
