In addition, I will help you collect some classic quotations:

George Washington

Famous saying: Because swords are the last means to safeguard our freedoms, once these freedoms are established, we should first put them aside.

Precedent is a dangerous thing. Therefore, the government must be firmly in its hands, and any violation of the Constitution must be condemned. If the constitution is flawed, it should be amended, but it cannot be trampled on!

John Adames

Famous saying: human beings lost their paradise by stealing forbidden fruits. This is a lesson for thousands of years, but it has never been taken seriously. Moral reflection, wise sayings and religious terror have little influence on the country when they conflict with current hobbies, prejudices, imaginations, passions or whimsical ideas.

Thomas Jefferson

1. The flower of freedom should always be watered with the blood of patriots and tyrants.

Don't believe or deny something just because others believe or deny it. God gave you a mind to judge truth and falsehood. Then you can use it.

A free man can get knowledge from many other sources besides books.

People have been deprived of the right of autonomy for a long time. Now, it all depends on how we enjoy these blessed places harmoniously and harmoniously. Examples show that human beings have enough rationality to manage human affairs and the will of most people, and the natural laws of every society are the only reliable guardians of human rights.

Lincoln

Don't be malicious to anyone, be generous to all, and be firm in poetry and justice according to God's guidance.

I don't have to win, but I will achieve it. I don't have to succeed, but I must live up to what I have. I must support any right, although he and his position are correct, when he and his part make mistakes. Lincoln

We don't know what will happen in the future, it's just an analogy of past experience.

I attach equal importance to human rights and animal rights, which should be the knowledge of all mankind.
