Yep, I agree. 100% of people tell little white lies, not just politicians. But the false claim that an election was stolen, especially when used to justify an attempt to undemocratically seize power, is not a "little white lie."
If you consider the accumulation of "white lies" from all politicians, including Trump most of all, to be equivalent to a single deliberate conspiracy, headed by Trump, to steal an election, I'm not sure what to tell you.
