No. You don't know what the symbol means to any other person than you. There is no absolute meaning of a symbol.

You are one person in a world of billions, each with their own symbols and interpretations.

Burning a flag could be done for an infinite number of reasons. It could be a constructive ritual that ensures "purification", or "cleansing" or even "betterment" as in a metaphor with wrought iron wherein the heat and pounding shapes and strengthens the metal.

The Chinese burn goods (and paper models of goods) to send them to their dead ancestors.

Symbolic behavior is incredibly complex.

Attributing "4D chess" to Trump's actions is tiresome.

I love an America that has free speech, including burning the flag. That America is dead, assassinated by the President.

I love an America that has rule of law, not rule by executive order. That America is dead, killed by Congressional incompetence and pettiness.

I love an America where the President has limits on his power. That America is dead, killed by judicial inaction.

I have the urge to burn a flag to say: This? This thing that you are turning the country into? This is not America.
