I believe the ideas perpetuated by Philip J. Klass helped UFO researchers more than he harmed them. Klass is known for pointing out that there are a lot of fraudulent UFO sightings and to me that is the total truth. When looking at some of these incidents, even the videos we have now, they aren't real.
I do not think that the ideas perpetuated by Philip J. Klass did not hurt UFO researchers. A lot of his idea and beliefs were just as out there as most UFO researchers. So I don't see how he can be criticized any more than some of the other UFO researcher with ideas that are just as farfetched.
The ideas perpetuated by Philip J. Klass have harmed UFO researchers. This is because people already have doubts about UFOs. And when someone comes along who has a big voice in the media, they can encourage or debunk whatever they want to. Poeple as a result will then believe them.
Even though I do not believe in the ideas perpetuated by Philip J. Klass, I also do not believe that it harmed the UFO researchers. People are going to have different opinions and research when it comes to almost anything, it does not mean that they are harming other peoples research.
There is nothing to do to help UFO research because UFO research is a fruitless waste of time for people. UFOs are not real and, considering that for the past few years people have been carrying cameras around everywhere in the world, by now, if there were real UFOs, people would know.
