Not true. They were first published in Denmark in September 2005, but the furore didn't receive international attention until early 2006, after some Imams took it upon themselves to tour the Middle East promoting action against them.
Regarding the topic of this thread: I think it is certainly the case that some Muslims prefer not to debate. Many don't see it as being important (even though it provides an opportunity to call others to Islam), and some simply don't have the intellectual firepower to handle it. However, there's a flipside to this, which is that Muslims are only supposed to discuss the finer points of their theology if they are what is called "knowledgable". This discourages a lot of Muslims from debating, and they defer to more knowledgable Muslims to do the job for them. Unfortunately this means that the Muslim knowledge base tends to be held by only a few members of society.
Some Muslims take offence at any questioning of their faith and resort to threats of violence. These are the kinds of people who protested so violently in London about the Danish cartoons. Fortunately that particular breed of Muslim is not strongly represented here on the forum, and threats of violence tend to be met with disciplinary action by the mods.
Of the debaters mentioned so far: in my view Ansar Al-'Adl is the best debater here on the forum - he conducts himself with respect and uses logic and scientific knowledge very well. Other prominent debaters on the forum are Muhammad, Fi Sabililah and Ahmed.
I think Ansar does a much better job than Dr. Zakir Naik, who is revered by many members here. Superficially, Naik puts on a good show: his recall of Biblical and Qur'anic verses is phenomenal. However, his arguments do not stand up to logical scrutiny, and generally rely on the authority of the texts he promotes. Therefore, he is convincing to someone who already agrees with him, but not to anyone else.
So, to conclude: there are Muslims who are keen to debate, but you need to look quite hard to find someone prepared to do it in what non-Muslims would consider to be a rational and intellectually honest way.
Peace
