cantoresq:
If your puzzled by a mitzvah, why not educate yourself regarding its details until the chiyuv is satisfied to your satisfaction? Yes, you are correct, if not for our recounting it, Amalek would be long forgotten. And that is precisely the point; we are specifically obligated to recount it — Zecher Amalek.
If you feel that you would not have the streghnth to do the mitzvah, the solution is to streghnthen yourself to be able to carry out the mitzvah. This would apply to any mitzvah. Killing an Amaleki, is not a “issue in our religion to bother me.” It is an OPPORTUNITY to fulfil a chiyuv and a mitzvah. And your approach of “I hope never to come upon the opportunity be tested in this manner” is simply wrong. Its a mitzvah. Not an aveirah to avoid or be “tested” with. You should look forward to have such an OPPORTUNITY.
