At some point they'll just have to grow up.

As much as do the people that get offended by the word "gimp", I guess.

How do they feel about unix daemons or the FreeBSD mascot?

My parents were quite tolerant of my devil worship[1], but they did tell me to hide my BSD Unix books when religious relatives visited.

[1] I think they knew Beastie was a harmless computer thing, but they also thought the moon was the size of a basketball.

And never mention chmod 666 or fsck...

Angry/hateful often enough to cause trouble.

They use Windows Server.

When I was a teenager I wanted to try FreeBSD but got turned away by the daemon mascot.

I didn't want my christian conservative parents to keep berating at me as if I turned in to the devil for choosing a OS that has a mascot that resembles one.
