‘Some liberals’ - you mean all of blueanon? Democrats, Msnbc, cnn, etc.
It’s unhinged because this sort of Russophobia may very well lead to WW3 and nuclear armageddon. Also because it has no basis in fact whatsoever. It’s every bit as unhinged as the ‘The Jews rule the world’ one.
Russia stole the Presidential election by hacking DNC and Podesta emails for WikiLeaks to publish so Russian asset reality tv star Donald Trump would win? But also it was Russian bots and memes that did the trick? LMAO.
In reality, Clinton stole the primaries from Bernie and made sure her opponent would be Trump who she believed would be a weak opponent, by getting her media mates to constantly talk about him. This ‘pied-piper’ strategy was a massive own-goal. So she blamed Russia for her own failures and of course everyone ran with it.
