Don't underestimate the power of simply ALWAYS referring to it as "the big lie". They mindlessly repeat it in EVERY article written or sentence spoken.
They never use even neutral language. They make every reference include something about disproven or debunked or whatever, and just ignore anyone who asks how it was debunked. The truth is whatever they declare it to be.
I could care less how often they repeat THEIR lies, I rely on common sense and evidence, not on unsubstantiated verdicts.
