I used to write with lots of caveats and such. I had to stop.

Was it because it was hard to read? No. It was because it didn't matter.

It doesn't matter how much you water your prose down with caveats and exceptions and criteria and clauses, it turns out that there's still a percentage of people who won't read them and still flame you. It doesn't matter how humble a tone you strike, some people think you're being arrogant simply because you have an opinion.

It's really not worth gumming up prose with exceptions, because English doesn't have the requisite level of precision anyhow.

Of course, I don't follow this principle 100% either, but I've stopped stroking out about it. Better to say something clearly and be misunderstood than say something muddled and still be misunderstood.
