You do remember Ralphie ends that story with an eyepatch, right? Exactly as people kept telling him would happen that BB gun and his carelessness with it cost him his eye. That rifle will take a lot more and the over-penetration of his skull and the walls of his house leave ample chance for somebody else to get that same bullet in them. But the highly communicable disease going around that's the reason you're not supposed to have large gatherings? That'll do over his whole family, everyone who comes to visit, and everyone they pass on the street who take it home to their own family who pass it on again.
You're less mature or mindful of reality than the movie character you reference. You're also playing with more danger for higher stakes and showing even more contempt for the adults in the room telling you straight what you're really setting yourself up for and who you make pay the price along with you.
And that's not even addressing that you're deliberately mis-stating facts as Christmas itself is under no threat. By all means put up the tree and pretend that underneath the comically rabid consumerism and general posturing it's actually all about Jesus, not the message you want to send that your norms are the only valid ones and religion is the horde with clubs that you will wield to bludgeon anyone who doesn't affirm your life is lived the only correct manner. That your neighbour up the block celebrates Festivus instead has no bearing on your life and current pandemic measures don't mention squat about any holiday spirit.
It's only travel plans and parties larger than the family already under the same roof that are hindered in any way. But since a quiet Christmas with the family is such anathema to you I guess we can cross family, good will towards others, and the basic appreciation and respect for the people around you off the list of things Christmas is about.
My guess is the real problem here is that no matter what it was you were planning to do over the holidays someone theoretically may have told you to think twice about the immediate consequences. And you never really grew out of the "but I wanna and you can't make me!" mentality.
Edit:
And I just noticed in the picture the over-capacity electrical socket is even sparking dangerously. That is way too on the nose as a metaphor for reckless disregard and self-destruction. To perish in a fire of your own making after working to overcome a design to prevent you from doing so. Is this subtle detail meant to change the meaning entirely and reveal the intent as satire of this madness? Or is your subconscious screaming at your higher brain functions and survival instincts to wake up and hit the brakes?
