Are you talking about the theory of Russian interference? If so, that is not the same as denying the results, that is questioning the integrity. The difference is huge. The later calls into question bad actors and asks for reforms going forward, the former calls into action the removal of the elected president in favor of the looser.

Now as for the conspiracy of meddling with the election. I thought that was pretty well documented fact. We have stuff like the Cambridge Analytica leaks that show actual manipulation of voters.

Maybe you should look into how the US meddles in foreign elections. It is something countries do to each other. Russia has always done that and so have we. There was nothing special about 2016. These complaints about CA are the left's equivalent of when the right says there is mass voter fraud because of one or two minor instances of election fraud.

I don’t understand, do you think we should have blind trust in election, that there shouldn’t be partisan and independent observers, that security measures shouldn’t be scrutinized? And if we find a fault, we shouldn’t call for reforms. We should just “trust” the system?

No, this is not the same as denying the results without evidence. There is no equivalence here.
