What we have is an anonymous user who made a stupid comment. They got modded offtopic, even though the comment had relevance to the article (vaguely). It was then modded underrated (a bit stupid if you ask me).

Then another anonymous user made a comment about wasting mod points. Modded offtopic.

The question is, will the third anonymous post also be modded down?

Stay tuned. Mods wasting good mod points on Anonymous users. (If you're just going to waste them, give them to me and I'll make *good* use of them.)

Edit: I just realised I can edit things. Here is another example of stupidity.

Meh,

Honestly, I don't participate in this...

An off-topic comment gets modded troll.

Question is, will the following two comments also get modded down? Or just ignored?

Stupid racists.

For your infomation I place people on my foes list who have signatures I don't like. Actually I also place people who has signatures that I agree with but have problems with.

example : "Food not Bombs is a nice platitude but it breaks down when you notice that the Bombees are usually well fed"

The problem I have with this signature is that it is like saying that charities are a nice platitude, but it breaks down when you notice that the volunteers are usually well clothed/feed/etc. I participate in Food not Bombs, as do many others I know. One reason we are well feed is that we dumpster dive (skipping for UK readers). We are living the philosphy of reducing waste, by eating what would otherwise be taken to a landfill. What is wrong with that?

Smash the state!
