Of course. In many circumstances, the experts don't even agree. It's incumbent on me to inform myself, and I can lean on those very experts, but I'm not at all comfortable ceding how to weigh those tradeoffs to the people who identified them scientifically.
I'm not necessarily saying you ought to cede to the experts, I'm saying you ought to do the research they have already done if you expect them to take you seriously about changing the way they do their jobs.
Obviously it's not breaking any laws to post an uninformed opinion on the internet, but what is going to be accomplished by it?
