Problem in your logic:
Not everyone who drives drunk will have an accident, therefore driving drunk doesn’t cause accidents.
Not everyone who had gay sex caught AIDS. Therefore, gay sex doesn’t cause AIDS.
Actually, being drunk doesn’t cause accidents. But it does make you more likely to do things that will cause accidents. Like driving in the opposite lane.
And homosexual sex does not cause AIDS. AIDS is caused by the HIV virus. But homosexual sex is certainly one of the chief routes for spreading the HIV virus.
It’s a question of Causation vs Correlation.
All of the Cancer researchers that I work with assure me that nobody knows what causes Cancer. If the author of this article does know, he should apply for a Nobel Prize.
Believe the point was that ‘consensus’ != science.
Problem in *your* logic:
Gay sex does not necessarily mean one will contract AIDS/STDs (drug user vs. transfusions vs.....)
More correct would be:
Not everyone who has promiscuous sex catches STDs. Therefore, promiscuous sex doesn’t cause STDs.
Still, even being logical (asking them to point to THE model that is the ‘correct/good’ one, or showing the multitude of times in the past where the ‘consensus’ was wrong [sun revolves around Earth/etc.]) does NO good in face of a zealot. This is dogma to the Socialists and CANNOT be logic’d-away
