It was hard to find examples of things I'd consider bullying in your post. The only thing seemed to be being screamed at once, which I agree is unacceptable.
Everything else seemed explainable as you having had an early disagreement with someone senior to you that led them to initially question your competence, and perhaps assume you are arrogant; they're continuing to do that, perhaps also to people senior than both of you.
(You also mention something about how you can't be sexist because you're a feminist, which seems a weird thing to say. In my experience everyone's somewhat sexist, and the people you need to worry about the most are people who think they're immune to it.)
Switching to another team, talking to your Agile Coach, or even talking to the PO about it constructively all seem like decent ideas to me. But you could consider the possibility that you simply made a bad impression and haven't taken any concrete steps to improve your relationship with them, giving them the impression that you're uninterested in doing so.
