I've read several reports recounting the history of other examples of dissidents entering public buildings.  The differences from Jan6 are rather interesting. 

Some dissidents have brought in & detonated explosives, some have brought firearms and have fired them inside congress.   BUT No, not for Jan6.   Yet several were carrying flags  Jan6. 

Violent examples:

• << Linda Evans and Susan Rosenberg, two left-wing extremists, along with five others planted a bomb outside the Senate chamber inside the U.S. Capitol, where it detonated and caused $1 million in damages in 1983.
• << A dissident Cornell professor smuggled three sticks of dynamite in a suitcase into the Capitol on July 2, 1915. It detonated after he left.
• << Puerto Rican nationalists attacked Congress on March 1, 1954. Five congressmen were injured by gunfire from the House of Repr. gallery

 Federal court houses  and other public buildings outside of DC have been invaded and threatened with arson during the Antifa/BLM riots.  No arson for Jan6.

Yet I did not read any examples except Jan6 where undercover Feds were seen encouraging people to go inside.  And we've seen the videos how doors were held open by officials, letting folks easily enter.

So Mark I'd suggest you're in good company in writing comments comparing Jan6 to other violent dissident events.
