A Pennsylvania amusement park pulled personalized bullet key chains from its gift shop after someone filed a complaint on social media, LehighValleyLive reported.

What happened?

Sarah Keller was with her children and their friends at Dorney Park and Wildwater Kingdom in South Whitehall Township, the outlet said, and while in a shop her youngest child stopped, pointed out the display, and said, "Whoa, that's crazy."

The souvenir was titled "Personalized Rifle Bullet" that showed a cartridge in an embossed leather holder on a key chain, LehighValleyLive said, with the words "The Right to Keep and Bear Arms" on the paper holder along with an image of an eagle.

"This is not OK," Keller told the outlet in an email. "We shouldn't normalize this."

Keller shared a photo of the display with her friend, Lisa Boswell, who then shared the photo on Twitter, LehighValleyLive said.

"Offering kids a bullet with their name on it at an amusement park gift shop is already the most ill advised thing to happen this summer," Boswell tweeted, according to the outlet. "Who greenlit this? Imagine a shooting survivor encountering this?"

The tweet has since been deleted.

"In today's climate — where our children are repeatedly asked to prepare for mass classroom homicide (lockdown drills) and can't play outside safely — it was inexplicable to me," Boswell said in an email, LehighValleyLive said. "Further, it showed a lack of sensitivity toward gun violence survivors."

How did Dorney Park respond?

Dorney Park followed up Boswell's tweet with a tweet indicating the key chains would be removed, the outlet said.

"We ceased offering the merchandise because we believe we can offer our guests products that are more suitable for our family friendly environment," the amusement park said in a prepared statement, LehighValleyLive said.

Then another kind of backlash hits

But once word hit that the bullet key chains were pulled, some Twitter users were none too pleased:
