How could that surprise anyone, when not beliving in the First Amendment's right of free speech???
“...not beliving [sic] in the First Amendment’s right of free speech???”
FreeRepublic has no constitutional requirement to post anything you choose to write. And if you check with the owner of the site, he has no desire to let people post anything they want.
In your case, I have complained about posts made disrespecting my wife, and the Admin Moderator has chosen to remove your posts. Most posters - including the vast majority of birthers - understand that family members who don’t post on FR are NOT fair game for derogatory comments. I am fair game, but my family is not.
If you think that violates your First Amendment rights...you are wrong. Again.
