Born gay is one thing. Racism is a learned behavior.
You got that backwards. Science has never found a "gay gene". There are a handful of genetic markers that might make a person more or less likely to be gay, but environment seems to be the big deciding factor.
On the other hand, racism could be distilled scientifically as in-group preference and pattern recognition. Both of these things are hard wired. In-group preference makes you more likely to help and defend people who look more like you versus those who don't, because that increases your chances of propagating your DNA. Pattern recognition means if you a lot of black dudes being criminals, your brain starts to think of all black dudes as potential criminals. In that sense it is learned, but it's more about empirically observing the real world than about society conditioning you.
