Planting Peace has erected a billboard in Cleveland that shows Donald Trump, the presumptive Republican nominee for president, and Texas Senator Ted Cruz about to lock lips.

Trump and Cruz nestle, their lips about to touch, under the headline “Love trumps hate. End homophobia.”

Cleveland is playing host to the Republican National Convention, which opens Monday.

“What Donald, Ted and the Republican platform either fail to realize, or realize and just don't seem to care about, is that their words and actions toward our LGBT family – especially LGBT children – have meaning and impact,” Planting Peace said in a press release. “LGBT children hear these messages telling them they are nothing but second-class citizens and are left feeling somewhat broken or 'less than.'”

The Republican Party's proposed platform has moved further to the right on LGBT rights than its 2012 platform.

Planting Peace is best known for erecting a rainbow-colored house in Topeka, Kansas across the street from the Westboro Baptist Church, which is best known for coining the phrase “God hates fags.”
