I can’t encourage, in good faith, that any wall should separate people… Just because you don’t agree.
Separation of church and state is one of the founding principles of the the “United States”. Just because people have different religions. Yours may be Judaism, Christianity, Islam, or even satanism. There should be a way to coexist. If not, it is a failure of the people, not the government.
Be the change you want to see, US government was established by the people, for the people.
Any failure of the US government to do so is the responsibility of the citizens.
Rights
Freedom to express yourself. Freedom to worship as you wish. Right to a prompt, fair trial by jury. Right to vote in elections for public officials. Right to apply for federal employment requiring U.S. citizenship. Right to run for elected office. Freedom to pursue “life, liberty, and the pursuit of happiness.”
Responsibilities
Support and defend the Constitution. Stay informed of the issues affecting your community. Participate in the democratic process. Respect and obey federal, state, and local laws. Respect the rights, beliefs, and opinions of others. Participate in your local community. Pay income and other taxes honestly, and on time, to federal, state, and local authorities. Serve on a jury when called upon. Defend the country if the need should arise.
But also…
We hold these truths to be self-evident, that all men are created equal, that they are endowed, by their Creator, with certain unalienable rights, that among these are life, liberty, and the pursuit of happiness.--That to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed, that whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate, that governments long established, should not be changed for light and transient causes; and accordingly all experience hath shown, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security.
Complaining on social media is not how this is done. Vote. Be involved. Lead, follow, or get out of the way.
