So you discriminating against certain race then? Racist? Wikipedia quote for you:

Discrimination is the prejudicial and/or distinguishing treatment of an individual based on their actual or perceived membership in a certain group or category, "in a way that is worse than the way people are usually treated."

Your last 2 question, yes, they are discriminating the other groups. Similarly, I am too in certain way.

You are behaving like a hypocrite too by saying you not discriminating them, but still saying bad things about their smell, behaviour and culture.

Hello, judging a book by its cover mean you judge a person based on appearance. In your case, condemn the whole race for some example you had. After reading few posts of yours, that is not judging a book by its cover, its like reading a page of the book and judging it.

Nah I know you are not an elite as you finding room mates to share the cost of your room. So, don't act like one and saying workers are worse off than educated people like you. Your boss will see you as worker like the way you see Bangla if you believe in karma. Don't believe? Look at the pay your boss or client for your photography job they paying you. If an elite with high pay, you won't be finding room mate here.
