If your place of employment considers stuttering to be "unprofessional" then that's ableism, it's as simple as that. Whether or not stammering is a disability is up for debate and opinions vary from person to person. I would consider mine a disability, but you don't have to. While there isn't really and sound evidence that you can ever stop stammering, and the possibility of stammering will likely always be there, I don't think this is the same as having to accept it and never doing anything about it. All stutterers have to do a bit of work accepting that itt will always be around, but that doesn't mean you can't find ways to coexist as it were. For me, in situations where I'm just talking for a practical reason, like ordering food or speaking to a receptionist or something, I write these things down and save speaking for when it's important, like in social situations when I really want to connect with people and you sort of need to do that with actual speaking. There is an element of accepting how your voice may sound, and coming to be used to it or even like it, but this can take time. Stuttering it stammering is probably the combinations of lots of different neurological traits coming together, so just because you family doesn't stammer doesn't mean you couldn't have inherited traits from them. People can also show symptoms of "covert" stammering where people (sometimes unknowingly) invoke strategies to manage the stammer they don't even know they have by substituting words like you described. That could apply to you or the people in your family. It might be interesting to speak to them, you might even find some covert Stammerers who don't even know they do it. As for people viewing you as an r-word, that is likely a case for self acceptance. If people will judge you on the grounds of disabilities of impairments then they are wrong for you. Many Stammerers will find that people make judgements about them based on their fluency, and all you can do in these cases is remind yourself that they are wrong to. All in all, there is an element of acceptance required given that most people stammer at least to some degree for the rest of their lives, but that doesn't mean that there aren't steps you can take to accommodate yourself and workout how to reach your goals.
