Did i handle this right?

Ok i was at the carnival today and i walked passed this little boy (probably around 7 years old) and his dad. Well the boy was telling his dad a story and he said "o did i mention i like boys not girls" Then his dad started yelling at him. I understand he is upset but i felt so bad for the kid. He is so young so he didnt know that its considered wrong to like other boys. They ended up sitting right next to me and the dad kept yelling while the kid was crying. Im only 14 so i didnt know if i should say something to the dad or if he would just blow me off because im so young. Also it really isnt any of my business but i just felt really bad for that kid. I know everybody is gunna think that he is to young to know anyway but he really isnt because i was about his age when i first started to realize that i liked guys and that hasnt ever changed for me. I just really need to know if i did the right thing by not saying anything because its really really bothering me because now he is never going to accept himself after seeing how his dad just reacted. I feel terrible for not helping but i feel like i only would have made things worse. Did i do the right thing or not?
