Spiders are good, especially in your house. They are eating something. Whatever they are eating, is worse than a spider.

It doesn’t matter what is true about most spiders, the point of the comment is about how most people react to the sight of one.

Is it the meme about normal people beating autists, autists beating psychopaths and psychopaths beating normal people?

[lazyasciiart]

No. It's that it doesn't matter that spiders are good, millions of people will crush them on sight.

[dooglius]

For example?

Somewhat orthogonal, but if the spider is not a Brown Recluse (if you live where those are), then it is competition for them.
