I’m not sure if you’re aware of this, but flags are inanimate objects that lack the ability to make conscious decisions like “storm the capitol.” People make those decisions, and people can carry whatever flag they so choose while doing so whether they embody the meaning of that flag or not, as evidenced by much of those same people also carrying conflicting thin blue line or maga gear. They could have chosen to storm the capitol carrying antifa flags, and besides the fact that you’d likely be cheering them on rather than admonishing them for the same behavior exhibited by your percieved enemy, the flag waved would largely be inconsequential to anything other than “your support.” In fact, you’d likely point out that ~1,003 have been charged from the incident which is not only a small percentage of the total supporters of either side, but is a small percentage of the crowd that was even at the rally that started it, meaning more people who fly either of those respective flags didn’t “do it” than did.
Of course, that isn’t propaganda-y enough for most, or is too propaganda-y because I’m only supposed to talk bad about one side not both. Oh well, c’est la pipe.
