Let's start arguments for householders's sake::
foreign people: who are they? outside nation! Then it's better you start explaining the boundaries in which an Arhant is bounded by.
ideal buddhist country: yeh! There is a ideal buddhist country in my dreams whose aura is so perfect that even i-> the dreamer, remains calm. Getting back to reality, even lion wouldn't kill, drunken becomes calm, even devdutta(father of modern hinduism and aghori) learnt meditation to some extent and received compassion from buddha-- whereas he also couldn't bring any harm to any arhant.
•••monks into slavery by force: Have you ever tried to know an arhant, the qualities of arhant, the respect of an arhant by consciousness.....? when an arhant says NO, no power of this universe can oppose, forget mere already-dead invader.
steal their resources: Since when did arhant require any resource to depend upon?
physically weak: One who is a conquerer of whole space, universe, sankharas, un-awareness, ya calling him physically weak!!!!
outnumbered: Since when did arhants are less in number? Infinite amount of non-materialistic (citta-body) devas, brahm, yaksh etc. protect them.... go back to point 3 also for this.
without reproducing: ya know reproduction only through a** and d***. What about reproduction through knowledge? It's amazing to know that sexual reproduction only produces those who can either survive or die, once out..... whereas knowledge-reproduction, once intiated, even if results in non-arhant, non-stream-enterer-- it continues for next birth also.
How is buddhism a proper belief?
Amazing, first know about an arhant.
when you rely on lay people to feed you and breed so they can protect you
Arhant never relies on anyone, it's for the sake of lay-people that they go for alms round, i.e. to spread dhamma, to give dhamma and to do that they require a medium, which is body. Lay ones, after receiving dhamma, helps them in their spreading of dhamma by giving them something to keep the medium(body) safe.
It's never meant to protect them, cause they are not this impermanent-medium.
I would suggest you to stand up against a wall and smash your head to force this MARA(over-possessing ignorance & defilements) get out.
FIRST KNOW ABOUT ARHANT
