Making the leap to assume that a person with any "particular" degree or vocation fully understands that area of study or vocation is also laughable. ... don't even let me start on the fact that we have no reasonable way to validate anyone's qualifications to post on any subject.
We all know "experts" in a particular area both in real life and on the internet that are anything but experts. At minimum, we don't trust those educated opinions.
Forums are good to find opinions but those opinions even from "experts" should be verified independently. However, these internet opinions can be a good place to start. Meanwhile, we are off topic. :)
