It can be done. Apologies if this approach was already here but I only say how to make text bigger.
Some of the ideas here will sort of work, but the web sites often override what you have set.
On FreeRepublic the way John R seems to have set it up, the browser largely behaves itself so you can set it in many browsers.
The problem is that the more modern browsers have started letting you pick font and font size, but not BOLD.
So you have to choose a naturally BOLD font.
For example, I use Brave a lot. If I go through the menu to the point where I can pick fonts, then the address in the web site bar (URL bar) at the top, instead of this:
reads this, and I have included edge browsers too
Firefox is a little different, just go to preferences —> general, and to the bottom to the font area. (You can override the web site’s font also in Firefox, but you probably will not like it on most sites, so do not check that box unless you want to try it elsewhere.)
brave://settings/fonts <—BRAVE BROWSER
edge://settings/fonts <— EDGE BROWSER
At this point, PICK A NATURALLY BOLD FONT. This may not be obvious.
The one I would try is
change Ariel to Ariel Round MT
If you have a FreeRepublic tab open, as soon as you change that in Brave or Edge or even Chrome, the FR tab will change and basic text will be bold! This makes it easier to test different fonts. Ariel Round MT is pretty bold.
Specially crafted text in some FR articles might not change.
Try that and see if most text in FreeRepublic is not just Big, but also BOLD. BIG and BOLD, sounds appropriate here!
