What is Racism?

One of the many issues I have recently is people saying that only white people can be racist. Please, everyone stop this ridiculous shit. The online free dictionary(www.thefreedictionary.com) that I always use gives the definition of racism as follows:

1. The belief that race accounts for differences in human character or ability and that a particular race is superior to others.
2. Discrimination or prejudice based on race.

Number 2 seems to be the important one. I would also add mistreatment to that definition however, since the words "Discrimination" and "prejudice" don't really seem to include all the things that are considered racist, and also leave a great many loopholes open.

So then, what we have for racism is: "Discrimination, prejudice or mistreatment based on race". Now, despite what some people think, race is a social, rather than biological, classification and is really very difficult, if not impossible, to define. It pretty much all boils down to each individuals opinion. What is that opinion based on? Almost exclusively on the colour of a persons skin. Other physical features may come into it, but colour is the main factor. So, racism winds up as being: "Discrimination, prejudice or mistreatment based on the colour of a persons skin"

Now, anyone saying that white people are the only people who can discriminate against, hold prejudice against or mistreat a person based on the colour of their skin is nothing more than a babbling lunatic who needs a serious reality check. White people can be (and frequently are! Check out the metropolitan police force's racist recruitment policy) discriminated against or mistreated simply for the colour of their skin, and that is racism.

Just one last point, there are people (one person in particular) who come out with the line "White people say they have no colour, so how can they be mistreated on the basis of colour?" to justify their own racism. Well, first of all, I aint never said that. So that kills the argument with regards to me. Infact, I have never even heard a white person say that. The second point is pretty simple, wether they say they have or not, white people do have a colour, and can therefore be mistreated because of it. If he wanted to, Prince Harry could say he didn't have any hair, but at the end of the day he's still going to be laughed at for being ginger.

Two of my YouTube video's relate to this:
