Experts - in any field - often have contradictory views. Get two economists in the same room and you'll have three different opinions etc. etc.
But that's because their opinions are often backed up by sound science or whatever knowledge field they are qualified in. They have their own professionalism behind it, lest it be their shame (no point being a scientist if you do not give professional opinion backed up by sound science).
One thing I notice here is that people will continue to shoot down science only because it is inherently uncertain. Science always works on the premise that you cannot be certain that something holds, but you can only be certain that something does
not hold. Ask a scientist whether something has no risk attached to it. Any scientist worth their salt will of course say that they cannot say that. The fact is there can be very, very little risk attached to it, but there is still risk. But most people say risk is risk, therefore it is unsound. Black and white. Quite unreasonable.
That is not to say that the technology may be harmful. Of course no one knows for sure - we haven't had 50 years of testing to back this up. Where do you draw the line? Wait 50 years to see if anyone has had cancer from this? Suppose we could do that. After all, that's how we started to become more aware of asbestos.
And, as you exemplify, it is possible for opinions to be
wrong. At one time, people believed the world was flat.
And back up your opinions.
And quite frankly there's just not enough of that. A scientist worth their salt will always try to back up their opinions. And some here are trying their best.
For some reason, anyone who is non-science of mind is allowed to have an opinion without backing it up for any reason whatsoever. Even if it is based on personal, emotional or religion, not many are giving good back up to their opinions. (And just saying, "It's a personal thing," hardly qualifies as a sufficient back up. I mean, we're not expecting three pages of formulas, but....)

You are not qualified enough to tell me my opinion is wrong. Ever.
We are just as entitled as you are to an opinion, which includes an opinion that your opinion is wrong.
You always seem ready to reinforce fervently your right to opinion (that everyone seems to be attempting to rob from you) and yet wanting to deprive others of their right to an opinion.
