How does it matter whether its 1 . 6 billion or 200 million or 3 . 7 billion or 1700 ? Selfdefense should applynot apply regardless of those numbers . The principle of selfdefense should apply the same . What you are saying or actually , candidly admitting is that you are afraid of their numbers . Which is very revealing . Its why Muslims behave the way they do i . e . 1 when in minority they play the secularism card and the human rights card but 2 when in majority they turn countries into Islamic theocracies and commit genocides and purges against nonMuslims . They know that they need to patiently wait to become the majority before they implement their genocidal theology . They understand that cowards like you fear numbers and know how to play the demographic game very well .
