The internet has so much potential for good, and not so good.
I have a friend, in his 60s, who regularly forwards politically charged emails to me. I usually can debunk them in minutes, and I send him the debunkings, and I don't hear from him again ... until the next email. This has been going on for years.
We all know, the problem with the internet is that if you're looking for something to confirm your opinions, it's out there.
