What are the most effective tools for establishing and preserving freedom?

There could be a number of answers to your question, as it is the sort of question calling for an essay in which you state a thesis and defend it. 

A possible thesis would be that the most effective tools for establishing and preserving freedom are effective legislatures and a fair and strongly functioning system of courts. 

Without effective legislatures (on the state and national level), laws and governance bog down and the rights and freedoms of citizens can be eroded by special interests or powerful individuals and groups. Without courts functioning fairly and firmly to uphold laws that protect citizens' civil rights and liberties, the freedom of all citizens can be compromised by those who have greater advantages of wealth or position. 

For another possible thesis, I would. point you to thoughts from Alexis de Tocqueville's famous work from the 1830s, Democracy in America. Tocqueville put great stress upon the direct involvement of all citizens in the democratic functioning of society, through things like service on juries in the court system and by their regular association with one another in civic groups. Tocqueville urged that in a democracy, individual citizens need to learn to unite in association with one another to work as a group to protect their freedoms against the encroachment of tyranny. Tocqueville said that the most democratic country on earth is, above all, where individuals have "most perfected the art of pursuing the object of their common desires in common." He thought there is a "necessary relation between associations and equality."

explanation:

because everyone tends to get their feelings hurt if they don't agree with something someone is doing and vice versa. it's a major issue that needs to be dealt with, especially in the christian society. everyone thinks that christians hate gay people, because it is a sin, and christians "just hate everyone who sins and every one is going to hell for sinning"(saying that all in a sarcastic tone but i'm just going to go ahead and tell you why everything with that type of view on christians is wrong.

#1. christians do not hate gay people. and if they do, then that is their own personal problem. christians are not supposed to hate anyone. if you hate a neighbor (or any person basically), then that is as if you are hating jesus.

#2. being gay is in fact a sin according to the holy bible. it is in genesis. and no, the fact that it is a sin, does not mean that god hates you. he is grieved that a person is sinning against his word, but he still loves that person. in fact, christians are supposed to love everyone. we are supposed to love our enemies, but hate the sin they are doing. we love you and respect you, but we do not agree with every decision you make, is basically what i'm trying to say.

hope this you ! (:
