“.... just one man bragging.”
If you really can do it, it ain’t bragging.
These counterfeit “Germans” of Islamic origin may possess a German citizenship on paper, but culturally they are no more “German” than a space alien. Their allegiance does not lie with a long and sometimes checkered history of great poets, highly evolved philosophers, or erudite scientific geniuses.
All that rich and varied background becomes nothing more than crumbling stones on which to erect mud huts and pay tribute to a greatly diminished opportunity for personal fulfillment or any kind of dream of personal advancement.
Islam is a decivilizing force, and while they may be able to apply the technology as it already exists, there shall never be incentive under Muslim influence to strive to make a more meaningful life, or to explore the technological means to bring it into existence. Islam is the ultimate Luddite force in the world, trashing and burning every historical artifact not of their making, replacing those icons with crude and poorly executed makeshift “monuments” to their determination to alienate and subjugate those whom they consider to be “lesser” humanity.
All you have to know about the insanity at the core of Islam is their lifetime obsession is to parade around a space rock.
