I think it makes it absurd indeed and even worse I think it has a overall negative impact. It completely disregard intent, a pretty extreme position to take for any form of communication. Now you are not using the definitions of racists, which opinion might be worth disregarding, you are also using fictitious ones.

You won't get through life without being hurt and learning to understand the meaning behind people using words is a skill you cannot skip to acquire. Misunderstanding happen and you need strategies to deal with them. It can but rarely results in conflict. You cannot expect everyone only using thoughts, associations and words you are content with. It is a false strategy without solution.
