Since when is criticising a country at all tantamount to hating it?
Also, I don't see any meaningful spin. Here is Trump, at a time when he has Hurricane damage, Healthcare debates in the summit, a Tax Reform and Infrastructure bill in the offing, and the ever-increasing tensions with North Korea and Iran, taking time away from such minutiae to focus on the important problem of sportsmen who want to protest about things they see as wrong with the country. Rightly or wrongly, they have that right, and it's both surprising and entirely predictable that Trump would rather talk about this than about actually important stuff.
