Why do Txt and Enhypen fans fight so much when they are “siblings”?

Fans of different groups in a company fighting is normal, but Enhypen/Txt fans have constant bad blood for each other, they are still fighting now on Twitter. Even though Hybe makes them interact as siblings, why do their fans hate each other?

wait were they under the same company?

Exactly because of that. Txt and Enhypen are both mediocre idols carried by company privilege, their fans know that one of them becoming successful will result in the other getting less attention from the company.

They fighting for who has the privilege of riding on BTS's coattails.
