As the lyrics say, " We are all the same, no one's to blame, it don't matter, if you're black, white, or yellow, if you're brown or red, let's get down to that love is color blind." Love is great. We can't deny it because of the difference. And it doesn't disappoint us. In the course of history, it transcends many boundaries, such as color, nationality, gender, occupation, etc. To be honest, that's the value of love.
Discrimination means to treat differently. But why do you treat it differently? Because you're not the same. Due to inevitability of difference, we can only change our attitude towards things. What we need to do is to legislate to educate citizens from an early age, and not to reject citizens of different skin colors, nationalities and cultural backgrounds, but to seek common ground while reserving differences.
