I usually don't care much about media outcries and the like, but I want to make one thing clear:
A derogatory comment =/= a discriminatory comment =/= a racist comment.
I feel the difference in meaning between these adjectives is starting to blur more and more nowadays.
Firstly, discrimination is treating people differently based on certain characteristic. You may just treat dude A better than dude B because his left toenail is longer. You are now discriminating against people with short left toenails. You may be weird, have an obscure fetish or whatever, but this is not racist or evil. Fuck, you even have something called positive discrimination. Discrimination is not bad on itself, everyone does it. Do you treat a complete random stranger exactly the same you would do your close friends? No. It's not normal, not natural and often times not even smart to do.
A derogatory comment lacks respect, it is critical and uncomplimentary. Even this is not evil on itself. If one of your mates gets himself pissed in some backway alley, gets his keys lost and you call him out on the complete drunken twat he is, you're being derogatory. You're of course justified in calling a drunken twat, but if you otherwise don't act differently to him you're not being discriminatory or racist. Even when you're the white guy and your mate is black.
Racism, in my book, is simply discrimination based on race. But I have to get my head out of my arse for that one. Years of misuse has changed its meaning to the belief that other races are inferior to your own. Even this is not evil on its own, just watch and compare the skin colour of swimmers and marathon runners. Genetic variation is awesome, it makes different populations on average better or worse in different areas. By the way, note the difference between population and race. The problem is that the current fuckwits are missing the keypoint of averages (and a lot of others points but I don't want to make a iron curtain of text). While all the final swimmers in may be of my glorious white race (or wtf that even means), put any average dude who claims whites are better in swimming against a black athlete and he will lose the race big time.
The single thing that makes those above three words evil, is a difference in power between the actor and victim. Western society is based on equality, and still holds that value alongside freedom in its highest regard. Nowadays our understanding and use of equality has effectively changed to offering equal opportunities for everyone. Which is also bullshit, upbringing, for one instance, plays one of the biggest roles in success. Nevertheless people like the idea. But at the point where the people in power are doing the above three things all aspirations of equality become lost. This makes us, the citizens of western and arguably even modern society, mad. It grinds our gears, makes us gnash our teeth and try to make this wrong right again. Sadly this effect is lately being used to censor opinions who are not even racist, let alone 'evil racist'. This only breeds more resentments and can turn men into actual racists, which holds another meaning entirely.
Alright having cleared that up, Trumps comment was derogatory, probably discriminatory but not racist.
The bigger question is: why do you want, or even let your head of state make derogatory comments to other sovereign countries?
Alright, have a nice night everyone.
