Should a therapist get edgy and correct you if you use occasional expletives?

I am going to an individual therapist for BPD, PTSD, Gender Identity Disorder.

I am usually so politically correct, or even silent in the groups we have.

I am Sicilian/French from NY where I learned it is ok to show ones emotions. I am now in Minnesota, often referred to as a very Passive Aggressive State. Emotions freak people out here. But I do like it here and need someplace a little calmer (and less expensive to be. I also have many strong interpersonal ties here).

Remind you, I am in therapy, this is a therapist.

I was upset and feeling backed into a wall one day and used an expletive, “bi*ch, referring in retrospect to someone else who was, from my perspective, being one towards me.

My issue and pain was ignored with a “don’t use that type of language, I don’t like that” from the therapist.

Moments of extreme stress are why I am going there.
In retrospect, I expected the therapist was someone I could trust and be “real” with. Letting my hair down so to speak.
Expletives are used when we are at wits end and cant’ come up with a “nice” way of saying what is going on. I expected the therapist to remember I am not always upset, I am doing things differently, growing so to speak, but I was hurting.

Is it not to be expected that the therapist pick up on my pain, address my issue with me and be understanding. Helping me out of the my boiling point so to speak, and not to correct me for being politically incorrect because they are sensitive to a word?

And again, I am the paying patient am I not?
And again, I am usually so polite so as not to offend anyone anyway.

Ughhh…...

If I am such a bad person
Maybe my past suicidal ideas were right and I need to be off the planet. (I am being factious there) I am pretty much over that kind of thinking (suicidal).

Any feedback
Please, if you are from Minnesota, kindly don’t respond to this question. (lol)
