Let me start by admitting that I'm not the fastest davener in the world.
Actually, that rather understates the point. I think I must be well slower than the median, because I don't remember the last time I actually got to answer physically to a kedusha rather than relying on shomeia k'oneh, unless it's been at my home kehilla, Shivtei Yeshurun, where we do give people considerably more time to finish their silent amida.
I can understand that different people will daven at different speeds, and I don't expect everyone to cater to my preferred pace. But as one who is more sensitive than most to slight variances in the speed at which the shaliach tzibur davens, I am a little disconcerted by what I perceive as a tendency specifically among "dati leumi" communities to pray at a much faster pace than "charedi" shuls. I don't understand why this is, because it doesn't seem to fit into any of the classical philosophical or political areas that are under dispute between the DL and Charedi communities: it's not about Medinat Yisrael; it's not about "Chadash asur min haTorah"; it's not about tz'nius; it's not about relating to the non-frum world. Tefilla (and kavana during prayer) is about our relationship with Hashem, and that's an area where it shouldn't make any difference whether you believe that the State of Israel is holy or evil incarnate.
In case anyone has misunderstood me, let me be clear: yes, this is a gross generalization. I know plenty of "dalim" who daven way slower than I do, and I know plenty of "charedim" who go so fast that I cannot believe they are actually saying all the words. But the general rule is that "dalim" daven fast and "charedim" daven slow. I don't understand why this is, and I'm hoping that you will illuminate me with your comments.
