Does it really matter what we call it? What's important is that Trump and his allies tried to prevent the transition of power through various means including...
Tried using "Alternative electors."
Phoning people to try to get them to alter votes.
Filed numerous legal suites.
He told Mike Pence to override the vote and then called him a pussy when he refused.
Lied to his base to incite a mob.
This mob tried hunting down Mike Pence and if Pence had left the capital, Trump may have succeeded.
Unless you're OK with all of this, I have no idea what the fuck your issue is.
