Even "true" pacifists like the Amish are parasites, because they can only survive in a robust and free society which will protect them from external dangers, at times with violence. This doesn't mean I despise the Amish. God bless them. But let's be clear: any persons or groups who depends exclusively on others to defend them are parasites.
Thats part of the hitch. They really don't ask for or want protection.
The one amish person I met was absolutley (and bizarely) okay with the idea that they could be wiped out. Some of them would do absolutley nothing but die if they were attacked. Yet I give them repect on one thing, some of them have served in the armed forces, usually in a non-combat role.
I don't know how that doesn't conflict with there religious beliefs, but I know they have done it in the past. I'll grant them this, they don't ask for, nor want, protections of the government in regards to there safety, they do not protest war, and they pay more in taxes they they could ever remotely hope to recieve back in services from the government.
Unlike the fake pacifists of today, who are not anti-war but anti-america, I have yet to see any evidence that the amish do anything but give respect to this country.
