You could apply their stupid, intellectually dishonest reasoning to almost anything:
Cars are dangerous, should you stop driving one?
You can burn your hand on the stove, should you stop using it?
Makeup/"cosmetics" were only worn by pagan women; why do 'sisters' use it?
Haircuts? Beards? Not supposed to to trim according the Bible
Jehovah's Witnesses don't think. They are literally intellectually brain dead. And they like it. You really can't help them until they decide to help themselves.
