Many want to invalidate Bryan's WWE run because they hate said promotion. Discrediting a wrestler's accomplishments because of the promotion they're signed to shows a lack of appreciation for that wrestler. It happens a lot with WWE stars in general.

Honestly, people want wrestlers who leave WWE to hate the company and I find it so weird????

Some people hated the company, which is fine. Some people are happy they were/are with the company, and thats perfectly fine too. People will have different experiences and they are free to share them.

But to expect a wrestler who left the company (whether WWE let them go or they wanted to leave on their own) to automatically hate the company is so fucking weird to me.

Like to go on their pages or livestreams and bait them into talking shit just so you're satisfied is strange.
