After Rick Santorum held rallies Friday in Arlington Heights, outside Chicago, police received reports of signs vandalized with anti-gay slurs.

Santorum addressed supporters at John Hersey High School and Christian Liberty Academy.

About 50 protesters from the Facebook group Carmel Catholic Alumni Against Rick Santorum protested the GOP presidential candidate's anti-gay views outside the Christian Liberty Academy.

“We feel it is important to counter Santorum's anti-gay hate, to set an example to students,” Matt Muchowski told the Algonquin Patch. “Rick sends a message of bullying, but we want high school students to know that other alumni send a message of equality.”

Inside the rally, two men were ejected for kissing each other. Fifteen minutes into Santorum's speech, the men got the attention of the crowd and began to kiss. They were ejected from the rally by guards as the crowd, estimated at 2,100, chanted “U-S-A.”

Timothy Tross of Lombard and Ben Clifford of Algonquin, declined to say whether they were a gay couple.

“I don't think the message should be about what my sexuality is,” Tross told the site, which is owned by AOL. “It's the message that he's saying about sexuality that matters.”

According to The Cardinal, Arlington Heights and Prospect police received reports of signs vandalized with anti-gay slurs. One “Stop” sign was altered to read “Stop gays,” while a “No Parking” sign was scrawled with “Fuck gays.”
