Hey, I'm just your average Triracial (European, African, Amerindian) Mutt.

What should I do?

I - Mutt Whiter and try to beach it out

Basically have Children with a White girl. It could be an advantage of not having a Shitskin family anymore, but I also worry about ruining the girl's bloodline

II - Mutt browner

Basically just marry a Favela Brown girl. On one side I don't have to worry about ruining no one's bloodline, but at the same time, I'll just create more Generations of Brown mutts

III - Just give up and don't have any children

Self-explanatory
