Equality House, a rainbow-colored house located across from the Westboro Baptist Church, a Topeka, Kansas-based group opposed to LGBT rights, was vandalized this week with anti-gay graffiti.

According to NBC News, the house, which is run by Planting Peace, Aaron Jackson's charity, was spray-painted with anti-gay slurs on Sunday. A few days later, seven bullet holes were discovered.

Jackson said that he heard loud noises coming from outside the house early Sunday morning and called the police.

“The Equality House has been a target for acts of hate and intolerance that reflect the same experiences our LGBT family face every day,” Jackson said. “Planting Peace frequently receives hate mail and even death threats, but over the past three months we have seen an increase in physical acts of vandalism and violence. While it may seem shocking to some, it's a heartbreaking reality.”

Jackson told NBC OUT that the house had recently received an “open season” warning from someone claiming to be a member of the KKK.

“In three years of existence, this is the most activity we've seen, beyond the regular incidents of people driving by and yelling anti-LGBT slurs,” Jackson said.
