Because the extremely stable genius sb prez used it as an excuse to foment promulgate HATRED. Remember the "take a knee" controversy? He salivated over it. He caused football team owners to bow down and bend to his will. He made good political use of it for his own benefit to manipulate people into thinking patriotrism resides in that piece of cloth. He ruined it forever more.
Why you ask? Because he always knows whatever he says/does his base will accept believe and spread. Like manure. He thinks it makes things grow. Actually it makes thing stink. He is very good at stenching up his surrounding and manuring those around him. He done did it toe American Flag. What else will done do it too before he's gone?
