Anyone who really loves God will treat any other human equally!
However, treating other humans as equals should be in the fact that they are human. Other than that, treat them according to what they do.
Everybody knows that if science actually saves, that it is only a tiny bit, and for a very short extended time-period. But right religion saves eternally.
This shows that believers in science have the wrong religion.
(And According to the bible, holding slaves are not wrong)
One of the reasons why Christianity is a good religion is, it attempts to get rid of slavery in a right way. What is the right way? It is by allowing people to freely become slaves if they want, and then to limit how harshly masters treat slaves. In other words, freedom yet protection.
Jesus said, "By their fruits you will know them." So, you treat bad people with love, but you be careful to not be hurt by them at the same time. Your evil protests against the Bible show that you are dangerous. Yet, out of love I am trying to show you the right path. At the same time, I don't open myself up to you in ways that you can hurt me with.
Some people use science for what it is meant to be used for... the technical aspects that step in the direction of engineering. Others - more or less useless scientists - try to predict all kinds of things from science, usually things that are way too complex for simple scientist science to predict. They are the ones who turn science into a religion, and they want to make themselves the high priests of their religion.
