Rockford, IL (LifeNews.com) -- There's an old adage, "If at first you don't succeed, try, try again." Pro-life advocates have tried 10 times to keep an advertisement they've taken out on a bus bench in a highly trafficked area of time from being vandalized. Abortion activists keep hitting it again and again.

A local pro-life group rented the bus bench three weeks ago and various pro-life message continue to be vandalized.

Abortion advocates spray painted over one slogan saying “Women deserve better than abortion,” and they have scratched off others.

A picture of a baby attached to the bench in another ad was stolen and the incidents have been reported to local police.

Kevin Rilott of Rockford, a spokesman for the pro-life group, told the Rockford Register Star newspaper he's disappointed that abortion advocates don't respect free speech.

“It’s just affecting someone and made them very angry,” he said. “We know it’s a controversial issue, but if we can't peacefully express our opinion, it’s not what our county is about.”

Rockford indicated the group has contracted advertising on the bus bench through November and will keep on putting up new slogans when older ones are defaced.

This vandalism follows several news stories across the nation where abortion advocates have vandalized pro-life property.

Pro-abortion students at Harvard University torn down posters the pro-life student group posted, subway signs in San Francisco have been repeatedly defaced, and pro-life students at Baylor University have seen their share of vandalism as well.
