Gaither's death has become a rallying point for gay-rights organizations' and state legislators' pushing a bill that would extend Alabama's three-year-old hate-crimes law beyond race, color, religion and national origin to cover crimes related to sexual orientation as well.

　　结构分析：在for引导的介词短语中，that引导定语从句来修饰bill; related to sexual orientation as well来修饰crimes.

　　译文：Gaither的死成为了一种推动力，促使那些维护同性恋权利的组织以及州立法委员去推行一项议案，使阿拉巴马已通过三年的仇视罪条文，除了涉及有关种族、肤色、宗教信仰、出身之外，也应该包括有关性倾向方面的罪行。
