Having a stutter is normal. Lots of people have lots of different things that affect them. Some people have asthma, depression, bad eyesight, etc. Yes sometimes it is easier to hide our stutters but when we are pushed back in life because of how people react to our pretty small inconvenience in conversation we should consider pushing back because at its core it is descrimination. Consulting a lawyer rarely costs anything but your time and will give you a better handle on your options. Best of luck :)
