You can bold text like this:

<b>Pope Benedict XVI</b> is an idiot.
Pope Benedict XVI is an idiot.

Note the backslash in the second tag to end the bold.

Or an underscore, with a similar end tag:

<u>George W Bush</u> is an idiot.
George W Bush is an idiot.

The underscore can be confusing, though, because it makes the text look kind of like a link.

If you want to really make a point, you could write:

<font size="+2" color="red">George W Bush puts food on his family!</font>
George W Bush puts food on his family!

HTML is pretty simple, but of course if one doesn't use it regularly it tends to get pushed out of the brain by more important stuff.

Oh yeah, by the way I agree with your post. Some people seem to think a War on Terror isn't causing enough suffering, so we need a Clash of Civilizations. I sure hope that isn't Bush's last gift to the world before he retires.
