I lie about my ethnicity? I'm white?

I wouldn't lie about who you are. I'd simply not talk about it. I'm 1/4 Native American. I claim it on paper work that I'm supposed to include it on. However otherwise I do not go out of my way to show that I belong to a tribe. I simply am. I attend some tribal activities, but for the most part I was raised just like everyone else with it being a part my heritage but not what defines me. If my heritage defines me I'd be so messed up and confused because I'm a mix of contradicting cultures.
