You'd have to work extreeeeeemely hard to show this isn't flat out racism
You really don't. You don't have to provide any evidence of anything you say. Ignore anyone who wants actual evidence. Fling a few well-worn phrases like "two-tier" around, comment that you aren't a racist you are just saving women and girls, mention "young men of army age", throw in a few "small boats", mix well and repeat over and over. If that fails, try swearing and personal abuse.
Apparently the tweet is down now, but the damage is done.
