Lindsay Lohan and her all-but-confirmed girlfriend Samantha Ronson are the latest Hollywood celebrities to take aim at Republican vice presidential hopeful Gov. Sarah Palin, bashing the candidate on homosexuality and other issues Sunday on Lohan's MySpace blog.

"I really cannot bite my tongue anymore when it comes to Sarah Palin," Lohan writes, urging people to vote for Sen. Barack Obama. "Is it a sin to be gay? Should it be a sin to be straight? Or to use birth control? Or to have sex before marriage? Or even to have a child out of wedlock?"

Lohan included a portion of an Associated Press story stating that Palin's Wasilla, Alaska, church was promoting a conference that promises to convert gays into heterosexuals through the power of prayer.

"Is our country so divided that the Republicans' best hope is a narrow minded, media obsessed homophobe?" she asks.

Lohan also blasts Palin on abortion (Palin is pro-life).

"Women have come a long way in the fight to have the choice over what we do with our bodies ... and it's frightening to see that a woman in 2008 would negate all of that," she writes.

Lohan also urges Palin to know her place — "Don't pose for anymore tabloid covers, you're not a celebrity" — and even quotes Pamela Anderson:

"In the words of Pamela Anderson, 'She can suck it,'' she writes.

In other Lohan news, the actress was heading into The Bowery Hotel in New York City Sunday night when she tripped over a metal barricade, TMZ reports. Lohan seems to have thought that a paparazzo tripped her — because she turned around and punched a photographer in the nose, the Web site says. Cops were called to the scene, but no charges were made.
