So, do you?!
DH is adamant that sweary songs l, or ones with vaguely racy themes shall never be on around our children.
Now, I don't really want the kids going to school swearing blue murder but my inclination is to just play what I fancy and not worry too much...
The only person I know brought up with prolific swearing is one of the most proper adults I know.
And I think it is our responsibility to offer a wide and varied musical education 
What's your policy ?
