Remember the little game of chicken and insults over Twitter with Kim Jong Un, that ended up with Donald Trump giving everything Kim Jong Un wanted, because he's an artist of "the deal"? (Trump did get a lovely letter in a giant envelope and swooned about it, remember?)
How do you only worry about what you read about Biden and his record on wars, where you even bloody admit that you're not really concerned about "his family benefiting from it", and IGNORE everything else that should worry you? Like a denial of the reality of the actual virus killing Americans (1 website says at the moment more than 243000 dead, that's like having a 9/11 number of deaths, followed by a 9/12, a 9/13, with two towers and 4 planes crashing every day all the way past Thanksgiving, with the latest being 2 more planes smashing into 2 more WTC-sized towers on a 12/1/2001...).
Let me try to answer why I think that is: you like Trump, for whatever reason (maybe you're racist, maybe you're brainwashed by Fox to think Biden is the devil), and you looked for a justification for liking him, and you found one when you read about him "profiteering from war". Good enough for you, everything else is irrelevant.
