Except that 99% of people who see that signature will think you have an
association with white supremacists.

Should they?  No.

Will they?  Yes.

The average person doesn't have a formal/mathematical model of trust and
what it means.  They have a loose, poorly-specified understanding, like
"only sign certificates of people you know well."  This leads them to
thinking, "well, this white supremacist group must know Chris well".
That's a false inference, but it's one a *large* number of people draw.

So you're now changing your statement: signatures *don't* always
strengthen the WoT -- a large number of them are irrelevant.  This is
much closer to reality.
