RBS:
You created a new halacha, that ונשמרתם involves only immediate threat to life. Either recognize this as a חידוש and take credit (and responsibility) for that, or provide a reference and citation for this. I do not believe this opinion at all, and would be shocked to hear this in the name of any posek, present or past. Shock me please.
In earlier comments, I referenced the sefer חיים ללא עישון. The poskim quoted in that sefer refer to ונשמרתם all the time, and there is not a single instance of this being an immediate threat. Do yourself a favor. Review what these Gedolei Yisroel say, and form your opinions once you have received their guidance.
