I'm going to say the n-word even though I'm half black
Why are you going to do that?
I've been fed up by all the racists and I'm like fuck them.
What is saying the n-word going to do against a racist?
I had to say it before someone else did and say it in a place where it will be recorded.
There is nothing about your plan that will help deter a racist. The only way to do it is to educate them on why words like that are wrong. Saying out loud yourself does nothing.
