I've had to boot a couple of younger people (kids-- I think the term "squeakers" is unnecessarily pejorative) from fireteams and both times is was because I found it weird to try and "socialize" with kids, especially in light of how sensitive folks seem to be about the potential for predatory interactions of that kind. Playing games like Destiny (especially tough missions/raids) can lead to emotions running high and frustration, swearing, and other "inappropriate" language that, while I know probably isn't new to most kids playing games online, still is something that kids shouldn't be hearing all the time from adults, IMHO. So rather than struggle to constrain my language and the topics that get discussed, I'd rather spend my free time relaxing with other adults, simple as that. Sometimes I drink a little alcohol while playing as well and that makes keeping up that "adult" facade even more difficult, lol. TL;dr: After watching my mouth and being "dad" all day long, I play games to socialize with other adults and playing with kids kind of goes against that and makes me feel like I have to watch my mouth too much. It's nothing personal, and I hope you can find other folks nearer your own age to play with.
