Welcome.
First read JimRobs letter on the home page of FreeRepublic. He if the founder of this website. We definitely do not agree on everything but we are, for the most part, all of a conservative mind in varying degrees and this IS a conservative website so argumentative liberals (usually liberals who "hit and run") are not tolerated.
If you stay, and if you behave yourself ;-), you may find that this is truly a great place to learn about the conservative mind.
Freepers are the friendliest, most down-to-earth people you will ever meet online. We are Christians, agnostics, atheists.
Americans, Canadians (see "Free Dominion"), Brits, Poles, etc).
Grandmas, grandpas, teenagers.
Stay-at-home moms, college professors, military, retired, authors, politicians, actors, truckdrivers, teachers, etc.
In otherwords - we ARE mainstream America!
Have fun!
Don't forget Jews.
...and union leaders. You forgot about union leaders.
