What happens to diverse theories?

I been thinking about this for about 2 years now. When it comes to theories or even timelines, it feels you have to include the mimic in so much to fit with other theories, or you have to use the books and even movies. Because I noticed atleast here and kinda twitter, that unless believe mimic everything or goddavid, 14 theory, Andrew or even fazburger, then your wrong.

Which is really annoying because it’s just feels like trying to be a fnaf theories person, you have to join a hive mind pretty much.

Which is kinda disappointing. Because I remember all the wacky theories people use to have but now it’s like almost every theory is the same. This is probably just me issue, which true I’m stupid
