I hate it when people do something like this, they replace the word to make it sound worse to prove their point. I get what you’re trying to say, but you’re ignoring the fact that stuttering is almost nothing like cancer in terms of what it does. You can’t practice being healthy to get rid of cancer. You can practice speaking to get better at not stuttering though. Now I don’t know if my post was the best one to do because it offends some people and is also ignorant to different situations besides mine, but I find it dumb to argue by doing what you did.
