Is freerepublic.com a Christian friendly site? Is it really just "Christian" republicans? Absolutely not, it's actually a Catholic Propaganda site. Don't believe me? Then then check out the clear evidence in this folder. It's anti-protestant, anti-Calvinist, anti anything that isn't pro Catholic (whatever the owner and moderators of freerepublic.com personally believe that is).
Does it matter? Yes it does, because the website name and many of the members of that site and it's supporters pretend to be tolerant loving innocent Christians when in fact it's used to spread the Catholic agenda be it godly or destructive. It's also a good reason not to bother listening to anyone on that site claiming to be a Catholic or who supports it and won't stop after being warned more than three times about it, and not wasting your time joining that website since your posts are first "reviewed" (for anti-Catholicism or non-comformism to the owner's beliefs) and you will be banned.
There is nothing you have to install other than a browser if you don't already have one to view what's in these folders and my computer isn't infected with anything.
