La Toya Jackson thinks a lot of Michael Jackson haters have had a change of heart since her brother died -- but it's unclear whether she's including Gene Simmons in that group.

You'll recall KISS got dropped from the upcoming MJ tribute concert in part because Gene has said he believes Michael was a child molester.

This weekend in Bev Hills we asked La Toya if she thought the concert should be off limits to artists who disrespected Michael. Her answer is all about forgiveness ... but are you buying it?
