What's to stop them?
The cops? A Walmart employee?
You appear to be in favor of me letting the "cops" take care of posts that I find objectionable.
Rather I say something about it, my own self.
Sucks that you do not believe in speaking up about objectionable things.
What you find objectionable is a personal opinion of YOURS - it is not fact-based. Your comparison of it to an overt act is false.
The bottom line is, whether you find it objectionable or not, if the posts made at Free republic do not offend the owner of the site then you have NO say in the matter. Although, I suppose you could always leave if it bothers you enough.
What's to stop them?
I don't know what stops them. But people do not cut in front of me in line at Walmart.
