@auramun@anarchism.space Also i have read from scientists explaining this. I myself am a published scientist and have even dealt with the subject before in a peer-review setting.
You just misunderstand the argument. It is the specific names and borders that are a construct (this is true) not race itself.
Try reading a peer reviewed scientific journal instead of some mass media news report for lay people. You will get a far better understanding of the material that way.
Also would help if you try to listen to people instead of going in guns blazing waiting for your chance to strike. It isnt a very mature way to behave.
