Apparently staff at the New York Times thought it was serious at the time:

You may consider them partisan, but since no one had won the election at that time, it's hard to figure out why they'd be "butthurt." Other organizations that apparently thought they were serious remarks include:

And so on. Your claim that everyone other than "butthurt" partisan democrats realized it was a joke at the time is incorrect. Certainly, democrats tended to hammer on Trump's remarks more, but that's just not relevant. Trump was not joking. He didn't sound like he was joking. Plenty of people thought he was being serious. And again, the Russians
did what he asked within a few hours of him asking.
It's irrelevant that it's anecdotal. Your claim was that:
To show your claim false, I need only come up with one counter example. I personally know of several, including myself. And now all the links above.
What, exactly, is this supposed to show? The Russians were indeed pursuing a number of angles. But they first started pursuing
this angle within hours of Trump's remarks. According to the timeline you've posted, the plot to interfere in the 2016 election began in Spring of 2014--over
two years before the Russians attempted to hack Hillary's emails. The notion that they were getting to it, but just happened to start right after Trump's remarks, is absurd. The odds of that being correct are so low they approach zero--there were press reports at least as early as December 2014 that her emails were a problem, and it was all over coverage of the democratic primary in late 2015 to early 2016. That the Russians would coincidentally start to pursue those emails, in context of the press coverage up to that point, is implausible. It would be like me telling the police that it's just coincidence my neighbor chose to kill my other neighbor an hour after I told him to do so--no one would, or should, buy such a ridiculous defense.
