Parashat Korach - TOO STRINGENT

Rabbi Yaron Reuven brings insights from Parashat Korach to save us from suffering the fate of Korach and his followers. Many people hear the truth of the Torah and want to do TeShuva, but their care bear rabbi cools them off telling them, "that Rabbi is TOO STRINGENT", "It's not for this generation" and other words of heresy. One of Korach's arguments was that Moshe Rabbeinu wasn't really teaching Torah from HaShem, and he accused Moshe of being too stringent and making up mitzvot. How can it be that Korach and 250 of the greatest Rabbis of the generation made such a HUGE MISTAKE and wound up in Gehinnom until this day, over 3300 years later??
