People love a good fight. I guess it is human nature. Sometimes people get caught up in controversies and disputes that they have no real stake in. This is ruinous and sometimes irreversible. Korach managed to manipulate others in to fighting for a "Cause" that was ultimately unjust. The fallout is well documented in our Parsha.
Sometimes it is best to just mind one's own business, for surely we have plenty to worry about without getting involved in things that are certainly none of our constructive business.
Shabbat Shalom
