I'm not sure how important that redirect page is, other than a fixed source page so that if anyone asks, it can be shown how many times people clicked through to an article from a story and to mask exactly what story page they came from. Since the front page links don't go to the re-direct page (why should it, it just shows the main forum page?) there's no warning, as you intentionally chose to use a link to another website.
I just opened Free Republic in Google Chrome. No problems whatsoever.
