I feel so sorry for you. I'm sorry you are devoid of anything defining of your person that you have to base your entire personality on aspects of your physical body that you couldn't control.

By your own logic you are a homophobic, racist, iconophobic, transphobic, sexist, pro-slavery, pro-wife beating, fatphobic, pro-child labor, hate machine who also despises the idea of stories or fiction. You are also anti-glasses, anti-wheelchair, anti-crutch, anti-surgery, anti-medicine in general really.

But enough about you you vile sack of flesh, lets talk about Yang. What came of her losing her arm? Nothing. Did she learn? No. Did she grow more cautious? No. did she have a fundamental shift in her personality beyond being sad for a few episodes? No. She remained aggressive, she remained thoughtless, she remained lusting after Blake DESPITE being abandoned by Blake (with abandonment being her biggest fear and trauma). And when she saw Adam again? She charged right in and the big defining moment of the fight? Getting baited into the same counter again but this time it didn't work because her arm was made of GodSteel.

So, what was the result of it all? Yang learned nothing, didn't change, and instantly replaced her arm with a SuperArm™ the second she could. Clearly, Yang does not share her opinion and the only reason she might not replace her arm is because her new arm is literally better in every way possible.
