And after The Lancet nuked any credibility that peer reviewed papers had, we should trust peer review now?
What are you talking about?
One piece of advice for dealing with someone who has obvious expertise in science: don't spring on them stuff you read on an antivax/anti-science website and expect them to know immediately what you are talking about.
The way such things *should* go down is that you would link to a blog that claims that Lancet has been discredited forever because of X, Y, and Z. Then I would read the blog and read the relevant Lancet articles. Afterwards, I would return and explain to you how the blog misrepresented whatever happened with respect to Lancet and what really is going on. Only then, when you cannot refute a single word of my explanation, would you get all upset and call me a Big Pharma shill/CDC hack/whatever.
This is how my interactions with people who have been hoodwinked by antivax/anti-science charlatans usually go. I have provided this sequence of events for your future reference.
