In this case, it's a little different for me. "is acceptable" to me means that it is generally tolerated or condoned, while "is accepted" is a more specific occurrence. I can imagine either of your sentences working, though.I also have a question concerning "accepted" and "acceptable".
What's the difference in meaning in those two sentences:
Watching this sport teaches children that violence is accepted.
Watching this sport teaches children that violence is acceptable.
or in general what's the difference between "accepted" and "acceptable"?
Thanks for your help!
