If I understand you correctly, you’re looking for a way to put some kind of provocative information in English up for your students to read and think about, and presumably to discuss. Do you mean put it up on the Web? A free web site would probably do you just fine, then – even one from geocities (and trust me, I rarely recommend them). Or you could do this on a bulletin board in your classroom.

I’m not really sure what a “mandex” is, so I can’t really comment there.

You might consider having them read a political website and comment on the articles there. On the conservative side, there’s

http://www.sweetness-light.com/

On the liberal side, there’s

http://www.dailykos.com/

Both publish things certain to (and, I think, designed to) drive the other side stark, staring mad.

Hope this helps.
