Do you agree with Centerfeud? Or has he caricaturized the Left's position?He's certainly caricatured (this side of the pond we speak English

, and caricature is a verb already as well as a noun) real opinions that exist on the Left, albeit mostly the extremes - I have seen all of these views expressed from time to time.
But that's no different, not typical, and no more accurate than me saying that the right are a bunch of fundie Christians who are trying to send the Middle East up in flames for no other reason than to hasten the Rapture, who oppose sexual deviancy in all forms but turn a blind eye to any kind of financial immorality, etc.
There are people that think like that, but they tend to be at the extreme fringes and therefore are non-representative.
That too is a caricature. It has to have some grain of truth, or else it wouldn't be recognisable, but it's not a full picture.
Is the Left too fixated on Bush and Conservatives to really deal with the danger of Militant Islam?Yes and no - some on the left are out to get the Bush conservatives as an end in itself - just as many conservatives were out to get Clinton.
But many liberals think Bush's stance on militant Islam - that there is a military solution to terrorism; that only ideological militants resort to terrorism; that active support for some absolutist Islamic regimes and active condemnation and threats against others in some grand real-world game of Risk - is not only ineffective, but dangerously counter-productive, and is helping to make more Muslims become militant in their views.
Is the Left failing to truly defend Liberalism?Only if defending liberalism is dependent on winning electoral power, which in large part it is - yes.
You can't stop a majority government opposed to many tenets of liberalism from removing or limiting some of them if you don't have enough electoral representation to mount effective opposition.
No sane political movement would try to filibuster EVERYTHING that doesn't go their own way.
Does the Left offer any good ideas for fighting Militant Islam? What is the vision of the Left and why would it work where Bush has failed?How about wondering
why militant Islam finds it so easy to win support, then taking steps to remove the threat by helping to provide positive alternatives, rather than merely threatening dire consequences for those that choose militancy? Carrot AND stick, rather than just stick?
Maybe it's about poverty, lack of opportunity, and lack of representation?
So maybe a left-leaning US government wouldn't be so opposed to international debt relief, removal of inward trade barriers to the Third World, and removal of support from non-democratic governments because of political convenience - most notably in Saudi Arabia, Indonesia and Pakistan, whose supply of the world's most virulent and active Militant Muslims is not perhaps entirely coincidental with strong US support for unelected and oppressive regimes with deeply suspect records on human rights.
In large part, conservatives don't believe that such things would work in principle, so they haven't even tried them.
