Scary theory about aliens (pt 2)

Ok. Or consider the following. There are two types of civilizations in the universe we will call them civilization A and the second civilization B. then we have civilization C this is the first civilization to gain space travel, interstellar tech, ect. Let's assume civilization A and B are both at the same technology level say a level 1 on the Kardashev scale. A civilization who is new to the stars but has developed to the point of full energy utilization BUT civilization C is a type 3 if not a hypothetical type 4, but without belief in the supernatural it's impossible to be a type 5 (for a type 5 exsample think Q from startrek). Utilizing what we know about human history refrinceing many of our conflicts especially those if the peleponision war, the cold war, and ww2 we can make a serise of assumptions. Civilization A is loud and wants intergalactic friends, it thinks if it can meet aliens its advancement would skyrocket. But civilization B is quite and has no interest in intergalactic politics and wishes to keep to itself. But civilization C sees civilization A as a threat. This is a natural assumption as any civilization able to harness 100% of its own solar system along with other solarium energys is a threat. So civilization C destroys civilization A before Civilization A can advance any farther. This leads me to point out that civilization B was not found by Civilization C and continues to progress until it to is a type 3 or 4 civilization which is on par with Civilization C. So it can be theorized that there are two types if civilizations those who are quite and go unnoticed and those who are destroyed.
