First step: Lurk. The answers you are looking for are here to find. But this board moves faster than any you will ever find on any part of the web, so don't feel like you have to try to read everything. Jumping up and down looking for attention is the first indication of trollism, so take some time and read and learn about how things are done here as much as learning the answers to the questions you have.
Second step: Read. Read the Constitution, read the Federalist Papers, read the writings of Locke, Paine, Hamilton, Jefferson and the others who founded this country. Be familiar with them and with the history of our Government. Sounds like a lot of work but you find that most on this board require facts and logic rather than feelings and impressions in our arguments. A knowledge of the history of our Nation and our form of Government is essential to put those facts and logic in coherent assertions.
Third step: Post, but carefully.
Hope this helps and Merry Christmas.
It does. Thanks.
