Don’t refuse to quote them.
Just don’t link them.
There’s no law that says you have to link what you quote. Just use a quote that fits within fair use, do your commentary, and deny them the link.
Me, I’m going to keep on doing what I’ve been doing. I think it’s good to give people the chance to read quotes in context. So I’m pretty much just going to ignore this little campaign on the part of the AP to frighten bloggers out of relying on the concept of fair use.
But if you’re bound and determined to punish them, just don’t send any traffic their way. That’s all.
