The argument you use to attempt to deny there is such a thing as "race", or call it what you want, is something I've encountered before. It's the same erroneous thinking that can lead some people to deny there is gender, because that's more "division" and "segregation".

There is a human species, and there are races that differentiate visibly. All you have to do is open your eyes and see similarities and differences, not deny them in fear that is separates everyone. Identifying with being an individual, then a man or woman, then a specific family, race, country, your human species, or all animal species, are levels or circles of identification that can expand. In no way does keeping a previous level of identification imply, impose or require that someone be segregating themselves, leading to conflict or doing the things you suggest.

Those are limitations of an individual to expand their circle of identification and valuation of others. When one goes up to larger encompassing recognition, identification and valuation, there is no need to deny or reject previous categorization. That is done in fear. There is nothing to fear in keeping an identification. The problem is in using a smaller identification circle to to justify exclusion of just and fair treatment of others simply because they aren't "like us" enough. I hope that makes sense ;)

Thanks. Peace.
