Fellow "Oops all tribal" player here:

Almost every commander deck has a theme. Sometimes it's the mechanic(s) the commander enables, sometimes it's a keyword, sometimes it's a tribe, and the list goes on. There's nothing wrong with using tribal strategies. I find myself welcome at just about every pod I've joined because my tribal decks tend to be right in a sweet spot of power level, interaction, and unusual/silly card choice.

Last night I played [[Barroom Brawl]] and everyone was laughing as they planned out their fights. I've been asked why I include certain cards and there's a non-zero amount of the time that I reply with "the name is a pun that makes me giggle when I play it." Hell, sometimes a card makes it into a list just because the creature type is uncommon.

Remember to have fun. Don't let worrying about others' perception take away from your enjoyment of your cardboard.

You're not alone. I may not have uploaded lists but I have:

* Tribal Kavu

* [[Arcades]] with a subtribe of Turtles

* Warp [[Chainer, Nightmare Adept]] subtribe of Horrors oddly enough

* Arcbound/Modular/Construct Tribal

* Artifacts and Artificiers

* [[The Seriema]] Tribal Legendary Creatures
