Monday's MarketFoolery podcast was a special "mailbag session" devoted entirely to answering listener-submitted questions. In this segment, host Chris Hill, along with analysts Jason Moser and Joe Magyer, respond to an email about investing in "socially responsible stocks."

The guys discuss how the definition of "socially responsible" is a highly personal one, touching on companies such as Chipotle (CMG 6.33%), Smith & Wesson (SWBI -1.02%), Altria Group (MO 1.45%), and Philip Morris (PM -2.96%) in an attempt to look at both sides of the coin. They also pinpoint the key factor in selecting socially responsible stocks for oneself. Watch the video above for the full discussion on this important topic.

Wal-Mart is one company that, for years, has dealt with accusations of "social irresponsibility." Whether you agree or not, there are two retailers with especially good prospects that are poised to give Wal-Mart a run for its money. You're invited to take a look at The Motley Fool's special free report, "The Death of Wal-Mart: The Real Cash Kings Changing the Face of Retail."
