If you are relying on logic to dismiss, excuse, or explain racism, I hope you will consider the following logical proof:

There is one race: The Human Race.

There are myriad things that make us unique as individuals, unique in our communities, in our cultures: none of those things are so substantially genetic that it would create natural boundaries that would prevent integration that would be described as separate races.

That is not my morality, it is science.

There is only one race, therefore any argument based on the argument that different races exist, is False and Invalid.

The differences that we state between us are the only unnatural things about us.

We have passed laws to separate us. Laws we created.

We have built highways and byways to separate us. Infrastructure that we invested.

We have created and ingrained mentalities that can only be called hegemonic to retain power structures that already exist and prevent new ones from appearing. These have only benefited the few.

All of those things were made by us.

All of the divisions have been made by us.

In out most natural state, I do believe, we are all one.

If you are the one trying to justify an argument of differences of race, then yes:

Your argument is a racist one.

It is inherently wrong, and invalid by logic itself.

But as you too are one of us, I have faith you too will see this.
