Race matters because it's the cumulation of genetic information of a species manifesting itself.
When people gather up together and start having a common origin and common goals and so on, they form a culture. This culture is indirectly related to race. Race is all the genetic information of a person.
It's not a good idea to mix very different genetic information. As fruit and vegetable is great because it's all different, and we do not just make "One", as nature doesn't, so human beings must allow themselves to form races and sub-races and stick to them.
The "Superiority" of a race is not merely decided by what it is, but rather, what it does, what it achieves, how much it advances or nor advances. Races can rise and fall in accordance to if they listen to the eternal Sanatana Dharma. Currently, Whites are high but on a decline, others are rising, while others are are high already but falling. This is the cycle of life.
People of a common race have common denominators in thought, behavior, biology, consciousness and so on. This makes civilization building easier, but this also ensures that different species manifest creatively different things. This creates plurality in ecosystems which is desirable by nature, because nature constantly tries to expand itself and it's creations in this way.
The universe tries to build for itself and discover itself through blueprints of creations, and each creation is distinct and has the ability to proceed in a unique path. The preservation of these paths genetically is what defines each creature from another creature, and furthers the attempt of nature to advance itself.
When there are decent blueprints, and not bad ones, it's a good idea to preserve them. Especially if they are creative, dutiful and so on. This is so that life can proceed in a good manner. When we "mix" things too much, we open ourselves up to risk and confusion, and likely to no upgrades whatsoever as a species.
