All of your post is well said, Jan. We have the right to our opinion, 
but we don't have the right to endanger others by acting out on the 
basis of our ignorance.

For nearly 40  I've been a member of the Standards Committee of the 
Audio Engineering Society, and lead author our Standards on EMC. I can 
report that all of our Standards are based on Applied Science, and the 
result of serious engineers who are practitioners in a broad range of 
pro audio -- broadcast, recording, live sound -- all with a solid 
engineering grounding. Those lacking that background, or with "an 
agenda," or to be unwilling to yield to others who know more about an 
issue, are quickly sent to the back benches. And all of us have an 
excellent BS filter. The goal is simple -- write Standards that make 
systems WORK, in the REAL WORLD.

One of the things that design professionals from different engineering 
disciplines do in design meetings is play "what if" scenarios to 
evaluate design decisions. A prime example in the real world I've often 
cited is, the design team of the Fukushima nuclear reactor failing to 
ask, or failing to have the imagination or education to come up with 
possible answers to the question, "What Could Possibly Go Wrong With 
Putting Emergency Power Generators in the basement?" In 2011, Mother 
Nature answered rather emphatically that question that should have been 
asked or satisfactorily resolved, but wasn't.  Note that this is an 
example to prove a concept, not an "attack" on anyone. I've been in lots 
of design meetings, and ain't nobody perfect.
