I joined a fraternity and really enjoyed it, stuttered my whole life. Friends knew I stutter, they don’t care. Just be yourself, be polite and friendly and you will find a good one. You can even disclose it if you want and see how they react. Most people don’t care how we talk. If someone is uncomfortable with it then just move on to a different one, they don’t deserve you anyway. Same goes for job interviews. Own your stutter and don’t let your stutter own you and hold you back from things you want to do in life.
