While I find statements like "kill all whites" to be hateful and unproductive, I'm certainly in agreement that such statements don't pose the same threat to whites as white supremacists ideologies pose to non-whites, largely based on the current power structures in the US and West. However I would caution you in your assumption that the same people who would "joke" about killing white people aren't also celebrating when death and violence is visited upon some innocent white person. From my experience there's certainly quite a bit of overlap between the two.

The specific instance of someone saying "kill all white people" on Twitter, at least the one I know of that caused a firestorm, I guess because its poster wasn't immediately banned forever by Twitter or whatever, was a joke by a white person. In poor taste? Sure. A credible threat or an incitement to real violence? Hardly. I will concede that sometimes "jokes" aren't really jokes...sometimes, they're the first step toward making an abhorrent idea a reality, and white supremacists know that and use it to their advantage by wrapping every evil intention up in a "it's just a joke, don't be so sensitive". Again, poor taste, sure, but not comparable to white supremacist gangs planning and celebrating murder.

I'm sure there are people who incite violence against white people, and people who would like to commit violence against white people. But, they don't have a voice in our society, whereas violent white supremacists do, and on a level they haven't in my lifetime. Just in the past week there have been three white supremacist terrorist attacks: 11 Jews dead in a shooting, 2 black folks killed in a shooting, and the unsuccessful bombing attacks. That didn't happen because those folks are white, it happened because they were perceived as being a threat to a particular way of life that has white folks on top.
