My uncle suggested using my misophonia to get through customs faster

So we were leavibg Nassau and we arrived at customs and in order to get through customs my uncle said "how about we chew in front of [name] and theyll see he gets uspet and we can use him to get to the front." And now im infuriated with him and i dont wanna talk to him. Like using someones condition to get to the front of a line is so so so disrepectful and insensitive. What should I do because it feels like no one understands, not even my own parents..
