No. I tried rereading my comment to see how you got that, but it seems fine. It was a very stupid attempted coup. You can't do a coup by taking over the capital building though. That's not how that works.
I may see how the confusion came. By "march on the capital as a protest", there's been many protests that use that term to refer to marching on Washington D.C., not the capital building itself. The comment before used that phrase to also include "to occupy the capital" referring to the capital building like Jan 6. That is not a protest, nor would it be achieve anything.
