:Personal attacks ("vanity") and constant racial references are not the way to go on Wikipedia.  

 :Dreadlocks do not belong to a particular race.  The article makes reference to dreadlocks amongst the very white Celts.  Also, your opinion on whether white people with dreads is natural or not is entirely irrelevant.  If you wish such a belief to be represented in the article, then find a notable person who has expressed it and quote them in the article.  You and I both no doubt find plenty of topics covered on Wikipedia to be unnatural, but that doesn't mean we get to censor them.  The fact is that whether it is a good thing or not, many white people have dreads.  In fact, the majority of dreadlocked people I have seen are white.  Therefore they will be represented on Wikipedia, as per policy. 

 :The ideal situation is to have one example of a white person and one of a black person.  This article has for a long time had a good pic of a white guy (until it was removed without comment by an anonymous racist vandal).  We are now just waiting for a pic of a black person.  When you find one, feel free to add it alongside the other picture.  I have no problem with you giving the pic of the black person precedence at the top of the article.  You just do not get the right to remove the original picture just because it goes against your prejudices (which is not an attack; we all have prejudices; the point is to rein them in on Wikipedia). 

 :Incidentally, your analogy about what pic to use to illustrate the article on Blond is rather poor, since if you take a look at that article, it has for many months been illustrated by a picture of a bleached blonde.  In addition of course, the analogy is poor because dreadlocks are grown intentionally no matter the race of the person, whereas a certain hair colour is something totally natural and unintentional that we all have until we resort to chemicals.  

 :The rasta pic has been listed on Wikipedia:Copyright problems and by policy you may not use it on any article until the matter is resolved.  It will either be deleted, or full copyright information will be found, in which case you will be allowed to add it to the article alongside the picture illustrating dreads on white people.  Alternatively, you can find another appropriate picture. 

 :On a generally point, I'd like you to review Wikipedia:Copyrights, Wikipedia:Neutral point of view and WP:RV#Revert wars considered harmful (the three revert rule).  —
