You are really casting the opposition to your argument in unfairly negative light. Stick to attacking his points, not hypothetical opinions you think he holds.

I would like to add that I think you are taking a very privileged (for lack of a better word) stance on the effect war has on our world still. Sure maybe in western counties war is minimal but there are loads of people you still live in war torn countries. I personally know a refugee who lost almost his entire family in the Bosnian War before fleeing the country entirely. To this day he can't hear about it without crying.

I think it is incredibly insensitive to prioritize other peoples experiences over theirs just because, I don't know, you hate foreigners or something. See, straw man arguments don't feel good do they.
