Yeah it's trash. She also got hit by Franky and people laughted at her. That's Oda for you. That's how bad BM has been treated.
The Franky thing was so bad alone and as much as I adore Franky, Jinbei and Robin, Jinbei shoulder throwing her and Robin literally rolling her out of the live floor or whatever and to the entrance of Onigashima is just absolutely frustrating. Imagine Oda trying to clown on other Yonkos or the Admirals or other top tiers like Mihawk like this?!
The anime made it even worse too, she was rolled down a MASSIVE staircase like she was a boulder/Sonic the Hedgehog/Chouji from Naruto etc and Toei dragged it out and emphasised it so much! OP really has become so childish now more than ever before...
It really feels like Oda wanted BM to be like a Buggy and Wapol of the Yonko, his "Yonko level gag character", sigh.
