I stutter a bit if I don't take my time and concentrate on what I am saying. I have a hard time pronouncing words with L's in them, so I understand and therefore would not be a problem.

Both just depend on how bad they are. Like if they are so bad that it makes it hard to understand them or hurts your ears. Then I probably couldn't. Though i'm one of those people can be like a broken record and end up repeating a word. I hate it when I do it but it's not that often.
The stuttering that isn't to bad would be like professor quirrell.
