The idea of flying the flag upside down became popularized by the movie "In the Valley of Elah" starring Tommy Lee Jones. It not's meant nor was it portrayed as symbol of disrespect to America but as signal of distress.
Our country is in distress from a regime that disrespects those that have served and sacrificed their lives for our country. It's about the changes that are occurring to the very freedoms that patriots have died for.
Others may have different ideas but this is how I interpret it.
