Tariq Ramadan is well aware of these problems within Islamic philosophy, as evidenced by his vocal appeals to reopen the "doors of ijtihad" to allow for new interpretations of Islam to escape the irrationalism of the principal ancient schools of belief. But instead of acknowledging those problems and ignoring the insurmountable philosophical obstacles posed by his own Islamic tradition, Ramadan shamelessly attempts to claim for Islamic traditions a commonality with the fruits of Western rationality.
Basically he's saying "Gee look, I know we are crazy, but isn't everyone" It's much simpler to compare Islam to the harmless crazy aunt in the attic that everyone can relate to. When in reality they have a irrational psychopathic cannibal in the basement.
Given Western cultures nearly complete rejection of absolutes, there seem to be little hope the confluence of irrational Islam and rational Western thought will not simply continue to erode rational thought to the point of no return.
The last election proves your point quite well.
Even with the general population obviously concerned about what exactly is going on in Iraq, to vote in a democratic congress with essential no ideas states or principled positions taken, besides Bush is a war criminal and he doesn't speak well, is pretty much irrational
