AITA for saying I would break up if she went to a bachelorette party with a male stripper?

(*EDIT: The question is AM I AN ASSHOLE.
Not THE asshole. She is fine. I am questioning only myself)

Before anyone assumes anything, everything I say here would also apply if the roles were reversed. If it was me in that situation, the same rule would apply.
Today I asked my girlfriend a hypothetical question: what she would do if she was invited to a bachelorette party where there was a male stripper.
She said she would probably go, as long as she didn’t do anything “excessive.” When she asked what I thought about it, I told her honestly that if my girlfriend went to that kind of party, I would end the relationship.

(**EDIT: I didn’t say that I would break up if that was her opinion, I said I would break up if she went. After knowing my boundaries)

After hearing that, she clarified what she meant. She said she would mainly go to support her friend (the bride) and be there for the party, not because she was interested in the stripper. She said she was thinking more about something like a simple dance, nothing sexual, and that she wouldn’t go if the guy was actually naked.
However, I was also very honest with her and told her I didn’t really believe the backtracking. Earlier she had used the expression “crazy stuff” (or “weird things”) to describe what she wouldn’t do. To me, that doesn’t sound like someone talking about just a normal dance. When people say they wouldn’t do anything “crazy,” it usually means there are other things on the table.
She then said that if it bothers me that much, she simply wouldn’t go.
I told her I appreciate that, but my issue is more about principles than rules. I want to be with someone because we naturally share the same values, not because they avoid certain things just to keep me happy.
(Edit*** : since I already responded in some comments, here I don’t expect her to be perfect in every detail, if she is the kind of girl that enjoys strip clubs and naked dancers she is not for me, that’s what I was meaning, (she is not))
I’m not looking for compliance, I’m looking for alignment.
Personally, I’m uncomfortable with the idea of that kind of sexualized entertainment being treated as harmless “fun.” For me it crosses a boundary in a relationship, and I’d rather be with someone who instinctively feels the same way.
After the discussion, she actually asked more about why I feel so strongly about it and tried to understand my perspective. She said she understands my reasons, and the conversation stayed calm the whole time even though we were both very direct.
In the end I made it clear that this is a very strong and non-negotiable boundary for me. She said that if she were ever invited to something like that, she would simply refuse to go.
So now I’m wondering: AITA for reacting this strongly and setting such a firm boundary?
Some people might say it’s wrong to “prohibit” your partner from going somewhere. I’m not trying to control where she goes. I just made it clear that this is a boundary for me, and that I wouldn’t stay in a relationship where this kind of thing is considered acceptable.

Edit 4:
Already answered 4 of these comments as well.

She is not the kind to do anything sexual, to my standards and moral, my girlfriend shouldn’t be in these kind of contexts at all,it’s not a problem.if she.would Fuck the stripper or not.
If she was the kind of girl to do so, she wouldn’t be anywhere near me

Edit 5: it’s a FAQ at this point

I saw a post on Reddit about bachelor bachelorette parties with strippers, got curious, asked her.
She does the same from time to time (she is not on Reddit tho she does that in Instagram)
