I am seeing several different ideas being discussed in your post. The first appears to be about how Muslims seem to be made the scapegoats for 9/11 and are somehow involved in a way comparable to how Jews have historically been treated. The second is about dialogue. I am not going to talk about this last one.

There is a bit of a misnomer about what a conspiracy theory is. In a way the phrase assumes a meaning different from the sum total of the words. A conspiracy theory is usually defined not as a theory about a conspiracy which is how it is often used here in the 9/11 forum (note: theory about a conspiracy carries an assumption a conspiracy happened), but rather a conspiracy theory is an irrational (unknowable) theory whose limits and circumscription (boundaries of definition) are extremely vague and often undefined to the point that it is impossible to create an adequate proof test. Conspiracy theories frequently assign hidden motivation to a group or individual in a way which cannot be debunked or irrefuted and are frequently (as in the case of anti-Semitism thru the years), a psychological salve used to "explain" events or "justify" a situation to force fit into a specific world view. Some people do this not because they necessarily believe it, but because it makes a good tool to mislead others in a way which benefits the misleader.

The reason why I will disagree with you about equivalenting post 9/11's bigotry with the multi-millenia of anti-Semitism has to do with the complicated nature of bigotry against Jews versus the highly simplistic one in the mainstream against Muslims.

Ignoring your statement about whether or not the 19 hijackers were not those men frequently attributed to the deed, the main conspiracy against Muslims at this time is one fueled by a simplistic understanding of the RW meme of "Clash of civilizations" which was often spread by the talking heads post 9/11 coupled with repeated graphic details of Taliban justice, speeches by Bin Laden, and the suicide bombers in Israel to generate an image where Muslims were unstable and likely to suicide themselves at a moment's notice in attempt to destroy the West. All poppycock of course, but also a very simple one which is likely to pass thru fairly quickly. Yes, there will be those who will spin off and create more virulent forms of this, but they will likely not have the same weight.

In contrast, Jews have had several thousand years of officially sponsored bigotry aimed at them. First there were many official programs against the Jewish religion by the Romans, Persians and the Muslims where they were blamed and accused of fomenting rebellion and deicide. Later with the rise of nation states along ethnic lines, Jews being ubiquitous and for the most part culturally distinct from the host population were accused first of being un-patriotic and seditious to ultimately masterminds of a great cabal ala the International Jew and Protocols. There is now a debate whether or not another wrinkle of anti-Semitism has arisen now following the foundation of Israel as a nation state and concerns itself with the notion that new forms of bigotry have been assigned to the ideas of Zionism and Israeli (such as being in a genocide against the Palestinians) or whether these expressions are just intentional conflations of the term "Jew" with more publicly palatable stereotypes of Israel and Zionist. All of this is still in play at the moment.

The other point I wish to highlight concerns the slight suggestion I'm reading into your post about exclusivity between anti-Semititic conspiracy theories and anti-Muslim. I draw this mostly because you only provided one line of thought in your post. I totally agree that 9/11 fueled the spread of many tailored answers designed to provide simple easily to digest answers to an extremely complicated reality and that this included a rise in anti-Muslim fear, but I also think that there are many examples out now where it fueled a rise in anti-Semitism.

Side note:

Larissa's accusation against the media and their treatment of Mel Gibson is a rather straight up example of a conspiracy theory as it attempts to assign a motivation to MSM which is ill-defined and thus unprovable.
