The Trump election has increased the prominence of flag-burning in the public consciousness. The thing I'd like to express with flag-burning isn't that the USA is particularly bad, but that the state in general is a problem (and the flag definitely is not sacred). So maybe it would help to desecrate the 'stars and stripes' alongside other flags. Or maybe, in limited circumstances, it would be possible to get the message across by burning other flags, such as the 'stars and bars' of the confederacy. Of course, if you burn the 'stars and bars' in Georgia, people might think you are burning the state flag.
