No it's not ok. Murdering other people is also in human genetics. Competition over resources is also in human genetics. What I'm saying is people have animalistic tendencies like jealousy rage and fear of the other. However humans can overcome these tendencies and be better than animals. We have the ability to be rational, and to learn. We have the ability to judge people based on their character rather than their appearance. If you stay mad at people for expressing a feeling or an emotion at some point before they were fully developed they are more likly to try and justify their actions actually pushing them further into that animalistic incorrect mind set.
