American History—a subject about which we've all learned. Those great American patriots who helped fight for our freedom. But what about those patriots whose great works have slowly vanished from mainstream America?

I fixed the grammar here, and reworked the 2nd sentence a bit. You might want to change it yourself, but you should keep it to where instead of just saying, "but what about those whose kindness," you should say, "those 'whoever,' whose kindness," or whatever endowment you wish to give them. I chose patriots again because it seemed the thing to do, but it was only my personal thought, not my recommendation. "Great works" is only a thought as well, not a recommendation, either.

I hoped this helps, and I hope I didn't overstep my bounds here.

Something we can all afford learning is American History. Great American patriots fought valiantly for our liberties, but their kindness has withered away from the bosom of mainstream America today.
