I disapprove of what you say,but I will defend to the death your right say it.的语法

题目

I disapprove of what you say,but I will defend to the death your right say it.的语法
我觉得这句话后半句的语法有问题.your right say it,是否应该改成your right of saying it?请懂的指教
这句话是句名言啊。这是原话，所以语法上应该不会有问题，但是我觉得语法上说不过去

答案

我不同意你说的话,但我誓死捍卫你说它的权利 to the death 词组至死；到底
I disapprove of what you say,but I will defend to death your right to say it
