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.
Let's translate from 18th to 21st century English:
Congress will not enact laws having the following purposes; to favor a particular religion, or to prohibit religious practice; to restrict free speech or the free reporting of news; to inhibit the right of people to gather together peaceably for any purpose; or to call on the Government to take corrective action in case these rights are violated.
It is not language that is at fault - it is the spirit of those who read not for understanding, but for personal advantage.
