I find this sad. I have played with a 9 year old boy who needed help with the very first mission. I am 54 and the lady who helped too is 42. We did not laugh at him for being a kid. As to your voice - hey it will change anyway and you can get all the revenge you want on them in Crucible if you do that. I am mostly PvE. Have your parents screen the people you play with and look for clans that won't discriminate or make your own. I was bullied as a kid living in a ghetto in Brooklyn, NY and fully understand how it feels. Thankfully you only get called names - I got that and beatings to go with it until I was able to give it back. The teens that do this are just immature. Don't let it get you down. My bet is that (again with your parents permission) you can play with more mature people who won't mind your voice one bit. If you were PS4 I would invite you to join us but alas - your Xbox.
