Honestly no big deal.

Shaq is right heat of the moment stuff and this shit been happening for year. Could it be seen racist? sure if it happened out of the blue whilst you eating lunch and some black guy said it to you.

In general the smack talk should probably tone done. I mean would you be offended with what harrel said more than if he took a shot at your gf? or say a brother that might have down syndrome or something?

Harrell apologised in the end because he thought he pushed the line with the smack talk and that is all that matters. No need to make it a mountain out of a mole hill.

Shaq is right, its just trash talk that since it was publicly scrutinized forced an apology, which was also the right move. It was a small situation quickly defused. No big deal whatsoever.
I dont see a double standard, the wording itself sounds more like a condescending jab than a racial slur, but read it however you like.

lmao are you 2 ignoring the fact the guy got called cracker i mean thats what the term he used literally is

We have to keep remembering that it isn't what you said but who you are and most certainly who you side with that will make backlash or not.

If you have played sports especially when it goes to high school, college and the professional level, trash talk like this is pretty common. Most times its used to get a rise out of somebody so they would get angry and do something stupid like take a swipe and get ejected. Since it was heard it was made a racial issue but in reality, it was a ploy to get Luk to get mad and probably do something stupid.

This reminds me of this:

This story is low hanging fruit because it’s a popular white basketball player or celebrity, but on principle I oppose double standards. However, there are far worse examples at a systematic level with double standards that relate to more serious problems and not celebrity sensationalism. There are real problems with black on white violence that are being lied about with groups like BLM which distort the facts of racism in our country or in western nations in general. I just don’t like the congratulatory attitude for apologizing when you could have just not done the thing in the first place? I think if a white person did the same thing they would be expected to go through some sort of social therapy and be more public about the apology in form of a written statement. There are many layers with double standards on race, but this is a bad place to start or end the conversation. 

What if Luka felt dehumanized by the usage of "white boy"?

He did apologize, didnt he?

That'd be some thin skin for a proffessional white boy NBA player tho.

Yer but this is the 21st century,  If you ask a friend who is a woman at work to get you a coffee it can be seen as derogatory/sexist/misogynistic  by someone looking in on the conversation these days. It is all about perception to the world and not the intent between two people.  

Hell, even graduates, get treated better than long time employees.

Hell, even some people find the word wife demeaning these days and expect you to call your wife your partner. I've had people snap at me because I asked how long have you and your wife been together. Get the crazy eye and they go well my PARTNER (in an aggressive voice) and I have been together for... One couple said wife is derogatory to me and not to use that word anywhere lol
