Proudly recall what happened in Pennsylvania 155 years ago — a divided nation shed the blood of 50,000 young men to answer the question of universal freedom and racial equality.

They called the Battle of Gettysburg the “High-Water Mark of the Confederacy.” It was a polite way of saying “the death of white privilege.”

So when five women recently were harassed off of a golf course only 25 miles away from this sacred battleground — apparently because they are black — it should horrify Pennsylvanians with any sense of heritage.

That’s reportedly what happened on Saturday morning, the Washington Post reported Tuesday.The women — who, according to local media, were experienced golfers and part of a group called Sisters in the Fairway — teed off at Grandview Golf Course in York County. The women told the York Daily Record that they were told by the club’s owners they were not keeping a quick enough pace.

That seems like a pretty tough determination after only two holes of golf and an hour’s delay from the scheduled tee-off time.

One of the golfers, Myneca Ojo, described the incident in a Facebook post:

“The owner tried to kick us off earlier on the second hole,”Ojo wrote. “The harassment continued to the 10th hole, with a claim we broke rules. We are golfers and we did not. We are professional women in our 50s trying to enjoy ourselves and were victimized, sectionalized and harassed playing golf.”

The encounter frightened the women, Ojo wrote, adding that they are paid members of Grandview Golf Course. She said the man who was harassing them — identified in the Washington Post story as Steve Chronister, father in law of Grandview owner J.J. Chronister — offered to refund their memberships and then called 911. It was a not-so-polite way of suggesting the women weren’t really welcome.

The Post reports that course owner J.J. Chronister has contacted all five women and apologized for the incident. That’s a smart move, but it’s unlikely to undo the damage done to her business by the viral nature of the news stories by the Post and other news outlets and Ojo’s Facebook post, which has been shared by nearly 2,000 people and viewed more than 80,000 times.

Butler County, here is an opportunity. Let’s extend an invitation to the members of the Sisters in the Fairway to come sample true hospitality. Let’s invite them to come play some great golf courses in Butler County.

We don’t need to dwell on the assumption that few golfers observe pace-of-play rules in these parts. Playing through is as ubiquitous as the “Pittsburgh left” — or used to be.

Is there an outing this summer that could benefit from the publicity of an appearance by this group of sudden celebrities? At least one outing, scheduled for August, has already expressed an interest.

Do the women golfers represent a niche demographic that our tourist promotion specialists would be smart to pursue? We can’t answer that.

Regardless, it would be nice to believe that racial discrimination and bias never got a toe-hold in Butler’s culture. There’s certainly no reason to allow such antiquated sentiments to linger today, a century and a half after the Civil War settled the issue.

Boiled down to its essence, what happened on the golf course in York County was just another form of bullying. We all need to stand up to bullies.
