From my strictly SEO-oriented point of view the most simple answer is: NOT, under any circumstances NOT, I repeat NOT to do what you've just done. You put an open link to the website you (and I too) disagree with from a descent internet resource (Yedda) thus increasing the popularity of that very website. It's one of the most stupid things to do to say this is what I disagree with a href. Have you ever heared about nofollow? You've just increased the popularity of that site by several degrees!!!!
Mind you it's one of the dirtiest and at the same time one of the most common Black Hat SEO tactics: to set up a hate site and thrive on backlinks from people who actually write against the materials published there.
On the other hand there is a lot you can do if a website is publishing things that are not legal in that jurisdiction. I am not a legal expert hence I can not pronounce any opinion about this particular website but in general terms sites publishing illegal materials including but not limited to hate sites, nazi and rasist propaganda, libel and slander etc. are usually in breach of their hosts T&C and thus can be easily taken down by sending a complaint to their hosting provider. Google as well is rather sensitive about these issues and I know of an example of a site that simply published a consistent critique of one of the well-known multinationals being banned by Google after it was reported (wrongly in my opinion) as containing libeloius statements. If none of the above works you can solve this matter in court as a final resort.
However, my personal stand on a more generic question - how to react to websites you find offencive is simply to IGNORE them. Freedom of speech is something I treasure and therefore I simply don't see myself policing the Internet or taking part in any action of a repressive censorship. I feel too tired for this
. Whatever negative action you may take against a site you disagree with will ultimately benefit that very site by creating a massive free publicity for it. The only positive way to fight the flow of information you think is bad is to create an overwhelming stream of good information. This tactic is a bit more difficult than simply to adopt repressive methods but is by far more effective.
