muslims aren't happy when they just kill the kafirs and each other. they gotta destroy any sort of ancient artifacts or statues, just like Muhammad did when he took over Medina, and eventually Mecca. because anything that existed before Islam is considered corrupted and useless to Allah. Therefore, it must be destroyed.
Islam is the purest representation of cancer. It destroys everything in its way, and leaves nothing behind. It kills people at an alarming rate, muslims and non-muslims, and obliterates any ounce of cultures, books, and history from the face of the earth. The sooner we wipe this barbaric religion off our planet, the better it will be for all of us.
