I will begin by saying that every argument or discussion, regardless of it's medium, always carries the potential for education, for anyone involved. People shouldn't be discouraged from discussing things on the internet simply because it feels hopeless. It never has to be hopeless, as long as everyone involved is willing to learn something. The desire to be correct rather than to merely take a stance and grab supporting arguments is the basis for rationality.
With that being said, let us discuss this widely-impactful topic with the rationality and reason it deserves.
As Gahars has already mentioned, Wrettcaughn, it seems you have committed a logical fallacy known as "
Shifting The Burden of Proof". You see, when you make a positive claim, such as "vaccines have the potential to harm", it is up to you to provide evidence to persuade towards your claim. It is not up to your opponent to provide proof that you are incorrect. Allow me to illustrate why this is.
Person A: "Grass is made of bacon."
Person B: "What? But why? How?"
Person A: "I guess you'll have to prove me wrong."
As you can see, this is illogical. Shifting the burden of proof can only work in a universe in which all claims are equally correct, which is not the reality of the universe we exist in now, for much the same reason that x/0 does not equal infinite; all numbers do not have the same value.
In addition, you must understand that extraordinary claims, such as those made by alternative (or, I should say, pseudoscientific) medicine, require extraordinary evidence. For example, the claim that grass is made of bacon would have to include comparisons of grass material to pig flesh material, and a precise match within those observations, adjusting for pan frying, of course.
Gahars also mentioned a point I would like to back up. Wikis are tools, but they require the same sourcing as any other academic paper. You can research the "footnotes" section to provide the crucial evidence behind each statement, which is partially what makes wikis such powerful tools for spreading knowledge.
Wrettcaughn, I hope you continue to have a fierce and undying curiosity about this world. It will lead you to wonderous places beyond imagination, and the more you know, the more you can create with that knowledge. Proper discipline when discerning the truth will help you with that goal. I suggest you start
here.
LessWrong is a wonderful website that will help you understand the fine art of rationality and learning, and even understanding more about the creature you are and your ability to comprehend the world around you. Have a look, aye?
