For me it's hard to counter that on the spot, and I thought a summary could be helpful that can be handed in to agencies etc. For friends etc. it could be helpful just to say "there's xyz, just google it". For doctors it could help to have an information leaflet (like that by Jamie).
But for authorities/courts it should have an official character.
@Snowdrop mentioned Anne Örtegren,
@Anne O. Anne used to make super helpful factsheets (I used to help her). Maybe that could be an idea for you to look into? The documents are all in Swedish, but maybe you could take a look at a few of them (using Google Translate) and use them as inspiration to create your own?
For these factsheets, Anne always focused strictly on the most solid facts and the strongest evidence based scientific findings, always using respected high-quality sources (like for example IOM/NAM, NIH, CDC, WHO, CCC, etc).
Here are a few examples published on RME's website (they keep getting updated, so the version you see when you click the links might not be Anne's original version):
This one is targeted towards doctors:
Utredning och behandling av ME/CFS (diagnosis and treatment)
http://rme.nu/utredning-behandling
These are targeted towards Försäkringskassan (the Swedish Social Insurance Agency):
Kort översikt över kunskapsläget för ME/CFS (short summary, what do we currently know)
http://rme.nu/oversikt
Funktionsnedsättning och prognos vid ME/CFS (functional impairment and prognosis)
http://www.rme.nu/funktionsnedsattning-prognos
Here's an article criticising CBT/GET (lots of excellent links!), that Anne helped create:

We also used to collect quotes and facts from major scientific reports and consensus guidelines etc, and saved them as documents ready to use -- for example by attaching to emails such as social security related applications, or when contacting journalists, or sending to a new doctor before the first visit etc. Also, they are super handy to keep as a reference, an easy way to find facts and quotes when you are commenting on posts on social media etc.
For example, one document we made was based on the IOM report, the IACFS/ME Primer and the Candadian Consensus Report. It listed many strong quotes from each report organised below headings such as "Quotes about the nature of the disease and its severity", "Quotes about pacing", "Quotes about retiring the term 'chronic fatigue syndrome'" etc. Also included in the document are full references including links, and a short description of each report.
The idea is for it to be as succinct as possible (short, easy to understand, quick to read) and to always refer to the original sources (the most solid and respected one you can possibly find). As you will notice, there is nothing in the documents linked above that says that they were written by Anne or published by the RME/a patient's organisation.
I hope this helps
ETA: I can PM you the document with the consensus report quotes if you'd like.
