People associate TOR with unsavory activity because TOR is used for unsavory activity. Running an exit node on a link you care about is insanity.

The main reason I have never run an exit node is fear that some overzealous LEO trying to make a name for himself is going to trace an IP off of a kiddie porn or drug market to my house and send in SWAT to break all of my windows and tie me up in court for months before deciding that charging me as an accomplice probably won't work this time because I didn't opt for the public defender.

Exit nodes only handle traffic leaving the Tor network to clearnet sites. Nobody is going to run a child porn site or drug market on the clearnet.

No, but they'll access clearnet child porn/drug sites through your exit node. Not every criminal uses Tor.
