Human rights are the most important component of a sensible conclusion on a political topic; not cultural sensitivity, religious history, civil privilege, nor any of the other complicated contributing factors to a controversial issue.
There are two reasons we need to ensure that our politicians come to believe this: a) by upholding equal freedoms alone, we set a powerful precedent which diminishes the inclination of any ethnic, racial, religious or economic groups to claim that they have been treated unfairly, and b) it is morally virtuous to uphold legitimate human rights.
In short, the principle of upholding all freedoms as enshrined in a basic libertarian concept is both the only morally valid and the best social philosophy.
