Would you say they'd be accepted if they were making more inroads into society?
Yes. I believe that if there were a massive migration of buddhists they would melt right in, at least after a generation or two. The political left has a point when it talks about the cultural melting pot. We did melt together into just "white people" or to a large degree even just "americans"/"europeans" but we once fought war with each other and even made racially charged propaganda about each other. I've heard leftliberals drawing comparisions with the current refugee crisis:

I can even see why they draw the comparison, but I think it only works in a free market environment (because people who seek employment have to integrate at least well enough to get employed and that is quite a lot (muslims not learning the local language or refusing to work together with women at work would probably starve or fly to another country under a true free market. ). I'm convinced that the free market fosters voluntary integration whereas forced wealth redistribution fosters resentment and fragmentation.)
I don't see how that ties in here. They never pointed at an enemy outside of the government itself, it wasn't really an ethnic or race thing.
In that case wouldn't it had been more accurate to say that they consider the government and possibly it's supports as enemies? Because you said that "Everybody that isn't exactly like you is an enemy and you need to deal with them." which to me suggests to be against everything foreign.
First of all, this was at the last supper. Jesus knew the events that would transpire. Serious crap was about to go down and he meant to prepare them. That said, he didn't walk in with a crate of swords. Advising people to take up arms against a clear known enemy and using the Church as a training grounds are two drastically different things.

I would argue it's less about being OK with them than it is either not being aware or simply not caring. Would you say they'd be accepted if they were making more inroads into society? Don't misunderstand me, I don't think Islam--which is the enemy of the day--is a good thing for society. What I'm saying is that non-whites wouldn't be "accepted" regardless. Asians are only half way there and they make most of our stuff.
