Dude, try again...
Those are Google links and it is Google that is generating the warning when you use Google’s search engine to find a particular FreeRepublic thread.
How Google handles what they consider to be an unsafe URL has nothing to do with my OS or browser. Neither my OS or browser provided any warnings about FreeRepublic.com nor did I claim they did. The entire point of my links was that Google thinks particular threads on FreeRepublic.com are unsafe as determined by Google - not my browser and not my OS.
I do have a clue.
You don't get that warning from google unless you are using their browser. Chrome or a varient.
So, um... like dude...
Yes, it matters what browser and OS you are using because Google presents differently to each and every one.
You have NO friggin clue what SGML is, or why it matters to the history of HTML.
