I never said they all had the exact same numbers. In fact, if they did, that would be proof of collusion and evidence for
your argument. But the vast majority of them showed similar results.

That isn't a handful of polls, that's almost
every poll for months before the election. You keep wanting their methodology, so feel free to take it up with that many different organizations; the burden of proof is still on you, not me.
Nate Silver has been very accurate before now, but something changed this year. Did almost every polling agency across the country deliberately manipulate their own polls, knowing that if Trump won it would call their accuracy into question and cause damage to their businesses? If so, why would they do that? Or is it that their data was skewed because Trump supporters decided not to answer surveys? Or was it something else we don't even know about?
Republicans have traditionally done better when turnout is low, and promises of a Clinton landslide would logically have driven down her numbers due to complacency. If you want to continue to claim they were lying without any proof, you need to explain why they would do that.
