If it isn't about the flag or national anthem then why disrespect both of them?  Obviously you are making bogus excuses.  BLM/Kapernick and other minority leftists say America(ns) is(are) racist.  That's why they disrespect the anthem and flag.  They call America racist based on the following facts.  Black leftists commit a majority of crime, forcing police to try to stop them, which can be deadly.  More whites are killed by police than blacks.  Democrats usually misrepresent minority criminals as innocent/peaceful killed for no reason and then riots/looting/damage and racist attacks ensue.  Based on these facts, minority leftists argue America(ns) is(are) racist.  The real problem is the mentality of leftists in thinking they are victims entitled to take what they want and otherwise deprive the rights of others.  Add anti-Americanism and anti-Caucasian racism to criminal minds and you have the mess leftists created.
