I swear I'm not racist. it's just an unfortunate circumstance.
I'll let you explain. What do you mean by "unfortunate circumstance"?
I don't think that I'm racist
If you don't think you're racist, you shouldn't say you are. Figure out what you're confused about it, and work to clear it up. Do you want people to think you are racist?
Maybe I chose my words poorly. I am not racist and I'm not sure why I said I am.
It's good that you are aware that what you said can be taken as something racist. You should think about what you're going to say before saying certain things. Sometimes an apology won't be enough to diffuse a situation.
