Plumber has truck. Plumber's truck ends up on TV being used by ISIS. Ergo, Plumber must be supporter of ISIS.

This is further harmed by it being surprising to people that trucks could be profitably shipped all the way to the Middle East.

This really frustrates me - because its 7100 km from TX to Syria, while Japan is 10000 km away. If you include things like convenience of shipping, it's probably easier to move things between Syria and TX than Japan and TX (because there is a direct ocean route that doesn't involve major canals or going around pesky continents).

"Plumber's brand becomes associated with ISIS."

"Better not patronize that brand out of an abundance of caution to avoid people thinking YOU support ISIS."

There's no requirement that people think that the Plumber's truck ended up being used by ISIS through anything other than an accident. But people are often very cautious and fearful and won't go out of their way to stand on principle, especially if, to them, it's something minor like which plumber they use.

1) A plumber in Texas wishes to publicly support ISIS with materiel and advertise NASCAR style, or

2) A plumber in Texas sold his truck to someone, and through a chain of sales, that truck ended up in Syria.

I really despise the population sometimes.
