I agree on all your points. The scientific community is not without its problems and there as sometimes politics involved and people are sometimes motivated by being published and so on and so. But on the whole, with all of it's problems and imperfections, the scientific process has given us so much progress, it's truly staggering. The thing is, most problems both you and I have mentioned exists mainly on the cutting edge of science when research has not yet piled on the evidence. That's why one study should not be considered sufficient data to prove anything. But there are so many established science findings that are being disputed by misinformed members of the public which the findings themselves have already been proven to a very reasonable degree with tons and tons of experimental data.
