I have some advice for you. Its not the best of advice in some peoples eyes.. I stutter too and I had to take matters into my own hands. Who ever picks on a person with a speech impediment is the person with the real severe problem. Morally and Respect wise.. You don't get any kool points for that.. When people violate me.. I violate them... I've always had a zero tolerance policy on how people choose to speak to me. The thing you have to do is make an example out of the next person that tries dehumanizing you. Now, I'm not saying choose violence but at this point you have to choose something that gets peoples attention. A person should have a sense of fear not to ever blatantly disrespect you like that. I had to do some demostrations on whats happens when i get disrespected.. I noticed that those same people that talk shit like that loves an audience.. so i give them one. I scream on them.. i basically yell at them infront of people.. I make sure its a big crowd. Because i know if i make a bigger enough scene.. I'll embarrass them instead 😂 😂 I'd be saying all kinds of crazy shit just for people to oull their cameras to come out. I'd have people scared to say anything to me on that campus
