Actually I'm Ashkenazi but since I'm secular it make very little difference to me. However not all ashkenazi jews follow this minhag. The rabbis who approve the continuation of this minhag do so for tbecause they object to any change and especially they fear that people might deduce that since kapparot is not necessary so are Terilin, Tzizit etc.
Last year I read that one of the rabbis wrote about kapparon. I think basically he was in line with the quotes which you have brought. However he also adressed the issue of animal rights and he said that there is no tzaar baalei chaim involved and without a doubt the salin chicken would be very happy to die for the purpose of redeeming a Jewish soul. I thought this is complete nonsense but my religious friend who is very clever said it makes sense from his perspective. And he also said that if he had been a cow then his wish ould be to become food for humans since that would fulfill the cow's purpose.
Zelhar,
You must be one who does not believe in Torah Baal Peh, or Orah Torah. It is very clear about the mitzvot of Tefillin and Tzittzits which you seem to brush off. These are VERY, VERY important mitzvahs and they are straight from the Shema prayer.
Do you say Shema? Maybe you should investigate this and discover that the Shema describes three important mitzvahs which you discount. The prayer which begins "Shema Yisroel Hashem Elokaynu, Hashem ECHAD!" contains the mitzvahs of Tefillin {Bind these words to your arm as frontlets between the eyes". Shema also contains the mitzvah of Mezuzah {Write these words on the doorpost of your house}. And it also contains the mitzvah of TzitTzits which the whole third verse describes.
From Aish.com @
http://www.aish.com/literacy/mitzvahs/Shema_Yisrael.asp
The full Shema is comprised of 3 paragraphs from the Torah. The first paragraph, Deut. 6:4-9, contains the concepts of loving G-d, learning Torah, and passing on Jewish tradition to our children.
These verses also refer specifically to the mitzvot of tefillin and mezuzah. While praying, we wear tefillin as a visible sign of G-d close to our hearts and close to our brains, to show that our every thought and emotions are directed toward G-d. The mezuzah scroll is affixed to our doorposts to show that we are secure in G-d's presence.
The second paragraph, Deut. 11:13-21, speaks about the positive consequences of fulfilling the mitzvot, and the negative consequences of not.
The third paragraph, Numbers 15:37-41, speaks specifically about the mitzvah to wear tzitzit, and the Exodus from Egypt. Tzitzit are a physical reminder of the 613 commandments in the Torah. This is derived from the numerical value of the word tzitzit (600), plus the five knots and eight strings on each corner, totaling 613.
The specific words come from Numbers 15:37-41 which read:
37 And the LORD spoke unto Moses, saying: 38 'Speak unto the children of Israel, and bid them that they make them throughout their generations
fringes in the corners of their garments, and that they put with the fringe of each corner a thread of blue. 39
And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the L-RD, and do them; and that ye go not about after your own heart and your own eyes, after which ye use to go astray; 40 that ye may remember and do all My commandments, and be holy unto your G-d. 41 I am the L-RD your G-d, who brought you out of the land of Egypt, to be your G-d: I am the L-RD your G-d.' {P}
If you dont believe this you are surely denying the very essence of the Jewish idea of mitzvot.

PS: If I am wrong please tell me, you may be one who keeps them but just dont understand why. I am one who happens to keep these three mitzvahs and feel they are essential for Judaism to continue to exist.
PPS: I hope the Rabbis do a good job of explaining the difference between Minhag {Customs} and Mitzvot {Commandments/Ways to come close}.
