That’s not a defense...it’s a reason. Having heard the lie and discussed it enables you to have a response at the ready. I may be a little slower than you, so I’m needful of the prep. Facts in a row, so to speak.
Of course, there is always the “don’t click on it”.
I think we all have a proper response to anything the progressive communist Democrats say. You’re correct most of us know everything they say is a lie. The other thing is, even if you completely factual response and provide the the actual proof, the left doesn’t care, one cannot reason with fanatics, religious or political. So the bottom line is you’re wasting your time trying to prepare to answer them, all they want is for all of us to die, they have zero inclination to try to reason with us. Thus I am somewhat suspicious of everything that looks and sounds like leftist inspired concern trolling like berlin_freeper used to do.
