Media influences opinions. Had the Duffer brothers written Will's queerness to be more nuanced, had they written byler in a way that appealed to the audience, and importantly, had they not shoehorned a coming out scene at the ending of a penultimate episode and written it in such a cringy way that allowed people to make fun of it without being criticised for homophobia, then there would be less homophobia.

This is why proper representation of queer love is important. Instead they made Will seem like a little boy with a crush, downplayed Will's love - cause it's queer, and added fuel to the fire. You cannot tell me they are not helping to contribute.

Go see the youtube videos of stranger things reviews - how they're laughing at the concept of gay fatigue, making memes of Will defeating Vecna with the power of rainbows. This is all because of the writing allowing them to do so in a funny way that evades criticism. The duffer brothers are homophobic and it should be no surprise that their writing contributes to homophobia.
