Am I the asshole for wanting my adoptive father to walk me down the aisle?

(Bella Swan x adoptive sibling)

I, 22 female/male/enby, was adopted by my stepdad, Charlie(44 male) when he married my mother. He has a daughter, Bella 18 female, from his previous marriage that recently got engaged to her high school sweetheart and they're getting married in August.

I'm also getting married in April, and I've asked both my mom and Charlie to walk me down the aisle. This enraged Bella because she says, and I'm quoting, "He's my dad! I should be the one he walks down the aisle! You're just adopted! Get your own dad to do it!"

My biological father was arrested when I was 3 a after murdering my 9 year old brother and for attempting to murder my mother and I. With his history of domestic violence and substance abuse he was given a life sentence.

My mom remarried to my dad when I was 5 and he's been my father ever since. He even did a little ceremony at the wedding where he vowed to be my father as he signed the adoption papers.

He was the one who taught me to ride a bicycle,  and drive a car, and tie my shoes, and he protected me from lovers that would break my heart. He raised me, and HE is my father in every way that matters.

When he and his ex divorced, she took Bella with her, and Bella dropped all contact with him when she was 9 years old. She only recently came back into his life when she was 17. She had moved in with him to finish off high school and that's where she met her fiancé.

Since Bella's moved back, she hasn't spent any time with him as she was too focused on her boyfriend. She doesn't treat him with respect and constantly acts as if his fatherly love and care is a a nuisance. She doesn't even call him dad like I do, she calls him by his first name!

So it was a huge surprise when she revealed that she wanted him to walk her down the aisle, everyone had assumed that she'd want her mother to walk her or for her to walk herself down the aisle.

My mom and dad tried to compromise with her and suggested that I move my wedding date for after Bella's wedding so she could still be walked down the aisle first, then he could walk me down the aisle on the new date.

Bella said no to this as she doesn't think it's appropriate for dad to walk me at all, and demands that I get my real Sperm donor (who's still in prison) to walk me.

Bella knows the situation with my bio dad, so she's not oblivious about how wrong her demands are.

I was pissed and told Bella that I would not be changing my wedding date for her, and I would have dad walk me down the aisle despite her protests because I wasn't going to bend over backwards for an entitled, narcissistic brat like her.

Now I've been getting phone calls from her fiancé, SIL, and mother calling me the world of names claiming that I'm being selfish and unreasonable about the situation. They're the ONLY ones stating this, and a lot of our family friends have dropped out of Bella's wedding because of her behavior.

I was not trying to ruin her wedding or her already strained relationship with dad, so am I the asshole?
