This is just incorrect. There is research showing that in an interview, stutterers are perceived the same as non stutterers, if they disclose their stutter in an interview. "A lot of phobias and causes of anxiety are 100% justified" This may be true but I hope this isn't just a rationalization of your own phobias and anxieties. In addition, I could have a phobia of public speaking, but then I actually get up and do the thing and for some reason, on that day, I kill it and don't stutter at all. Therefore, that anxiety and fear of public speaking wasn't justified at all. It's important to challenge your phobias, anxieties, or fears, rather than submitting to them. In fact, this is the only way to overcome them. Your comment projects confidence and i'm sure you meant well but you can inadvertantly be doing more harm than good with comments like those that may reinforce beliefs that people have about how they are perceived, and are just factually incorrect.
