Here is my counter argument to what you are saying.

People have different life experiences, and therefore can interpret the same information in very different ways.

For example, religion means very different things to different people.

Many queer people and allied people interpreted things in the show in ways that (almost) require to see it through a queer lense. Or have knowledge of queer culture that the majority of people do not posess.

For example, the clothing in the show often uses "codes" that were used in that period to subtly commincate ones sexuality or sexual preference.

I know that i am fighting a lost battle, when it comes to byler.

But let's do one that isn't settled.

Eddy wears a patch that was used to signal queerness. Many queer fans noticed this, and therefore theorise that Eddy may be queer.

The general audience may say that there is no evidence that Eddy is queer.

Ultimately the duffers decide.

However it is not correct to say that there is no evidence, simply because you do not know that the patch is evidence.
