I agree with most if the points from @____ . That's quite a name, while I disagree with some of his/her points.
I think personality and attitude is a very personal trait, tesaile I try to see each person on a case basis. Mero ramro indian sathi ni cha ani attitude dekhaune nepali sanga pani vet vako cha. Yo nation based garib mentality haraunu paryo. We say Indian this and that, but Indian ma dherai ethnicity ani sub ethnicity cha. It really doesn't matter who is what color. Euta s-indian ramro sathi cha mero, because he understands and is logical, hard working . Tara euta nepali thiyo ko sanga ali thak thuk paryo - you know why, because tyo nepali was a bully. Jahile ni hochaune, j garda pani yo tyo vanne ani mache ko agadi badar banaune. It was just building in me, and I just had to stand up and I did it very strongly. He just fucking lost the day I picked up fight with him (not physical but verbal) and i found many people in my support, because that guy was an asshole.
So, take your time to analyze the situation, do not act erratically. If you work hard and are genuine and are surrounded by hard working and genuine people around you they will realize, your boss will realize.
If you need to stand up take some time; if talking with that person helps go for it l, but here is a suggestion - If that person got too much attitude and has a bullying me mentality talking won't help.

If you think there is something you can do something (communicating, passive or aggressive approach) to improve your situation, go for it; think throughly. If you think negativity is inevitable, just move on from that work place.
Sometime fighting helps sometimes it makes it worse, sometime avoidance and ignorance are better. Take your time before you take any action.

Doesn't matter what country, color, ethnicity you are, we all are humans. I have seen bootlickers, morons and smart people in every color, ethnicity, even in degree earning people.

If a person hasn't been through really difficult situation in life to learn a lesson, he/she isn't going to be humble. There is much more for that person to learn.
If a person has always seen and learned to cheat and thinks that's the way to success, that person isn't going to be humble.
If a person hasn't had enough love in life, he/she isn't going to be humble.
Learn a person, and you cannot see through somebody over a bottle of beer. Take a approach you think might help, else move on. If you cannot win the situation over it will affect you.

Let us know what you ended up doing. Just for a lesson.
