Fundamental freedoms exist here in the United States, enshrined in the United States' Bill of Right's. The very first one (1st Amendment) being such a fundamental right:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
Per article Article 19 of the Universal Declaration of Human Rights:
"Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers."
One of the most common questions I get asked is where does this right end.
The only place I have ever seen it make sense is when another person is caused physical harm by the actions being "said" with an attempt at "freedom of speech".
It does not matter where on Earth you are standing, what country the soil under your feet hails from, or what ocean the water claims. For any person, no matter how big or small, no matter the size of their platform, that is the line in the sand.
We are not identical, our knowledge and response to the travails of our environment are going to be different. We may see different paths to handling the issues we see before us.
These rights are there to allow us to walk the path we believe will bring about more freedoms, more equality in rights and dignity to ourselves and loved ones. Feel free to walk your path.
However, never, ever allow that path to include the harming of another human being - the path with that on it, is not the right path.
