Should I feel angry at the random gym comment?

So I am tinny by size and I was working out ( I work out 8 times a week,gym plus something else ) Im petite but muscular,and a guy was standing next to me working out,so I asked him am I disturbing him ( as in,can he work out so close to me ) and he said '' nah,your too little to disturb anyone '' and urrrgh it just made really angry,I hate being underestimated. I know he probably didnt mean anything bad by it,and that its silly that Im even thinking about it,but was it meant as an insult?
