I hate to break it to you - but these people don't believe that. They look at Biden, they look at the propaganda on the BBC and CNN - and that's all. They don't look at the polling data or the underlying statistics, they don't look at the trends or the historical markers. They don't look at the verifiable information compared to the subpoena immune claimed "data". They have no experience with the actual election process. They don't know how to spot a win or a loss, they don't know how to interpolate or extrapolate. They have none of the tools that would allow them to easily spot a rigged election. Instead they rely on proclamations from the very institutions in thrall to the agencies that rigged the vote.
And they have no dignity so they are immune to ridicule.
You are onto a loser here I'm afraid. They can't be reached. Even if they wanted to be.
