One of the most disgusting memes continuing to survive among humans is Racism.
Wikipedia defines racism as -
Racism involves the belief in racial differences, which acts as a justification for non-equal treatment (which some regard as "discrimination") of members of that race. The term is commonly used negatively and is usually associated with race-based prejudice, violence, dislike, discrimination, or oppression, the term can also have varying and contested definitions. Racialism is a related term, sometimes intended to avoid these negative meanings.
Despite attempts to modify human behaviour through education, it seems racism continues to exist.
I consider myself as a human or more,a s an animal, so I hate being stereotyped as belonging to a certain race, religion, nation or region and I find it disgusting when people do so.
I identify myself as Anti-Racist, i.e. someone who is against those people who suffer from a racial superiority complex. I personally consider racism to be more dangerous than religion.
So my question is - How to eradicate Racism from society?
I think you answered your own question in a way.
You readily define yourself as belonging to one group of people, while despising another group of people.
This is basically the biological mechanism that drives the plethora of group exclusions humans (and why not animals) do. For example, sheep are known to exclude some lambs from getting milk because of their colour (can't find the citation, it is, I am told, a fairly common phenomenon though).
Now I'm not saying excluding or discriminating one group of people because of their skin colour or slightly variably physical properties is anything but stupid, or indeed comparable to discrimination of people based on their ideas, but it is nevertheless our desire to be with like and be wary of unlike that in my view causes this.
Think of it biologically. The absolute majority of our time on this planet as a species has been living in small communities of mostly related people. Choosing your friends based on people you percieve as "your kin" effectively boosts the fitness of your genes. This is due to the fact that in small groups that are related to each other, you share many genes. It's like the fact that, from the perspective of your genes, sacrifising yourself to save two or more of your siblings means that your genes through your siblings have gained from your sacrifice.
Today, however, society is very different. But we remain the same species.
I'm very much against discrimination of people, be the cause or reason (and I'm using reason loosely) anything at all. But as a biologist I'm a bit pessimistic about us being able to shake racism off anytime soon. It always seems to resurface whenever things start going badly. So maybe the best way to minimize racism is to try to see to it that everyone can feel included, has possibilities in life and that our economical systems don't fail. Oh, and a bit of education never hurt anyone.
