If you value humanity then you must be aware about the things they teach in school textbooks. Even they didn't spare science books. That's the reason even the educated ones feel that Islam is the only truth and Pakistan was created for a goal and that's Gazwa e Hind( I hope you will check what it means). Btw I didn't say anything about regional boundaries but as you have raised this point, you need to know there is no human civilization possible without nation state. You better read something about social Darwinism. All religions are equal is the biggest myth. A religion is an idea, an idea can be good or bad. Saying all religions are same is like saying all political ideologies same or all scientific theories same.
The race issue is also important. We rarely find actors from Bangladesh, Mayanmar or Srilanka or even from North East in Bollywood. If you have good height, sharp looks and fair color you are considered good looking. That's why the people of certain races are the only good looking people. Many of my friends like Pakistani actress , you see white girls as cheer leaders in IPL, these days even in the songs of Bollywood movies , there are white models and some actress like katrina kaif or Jacklyn fernandez are not racially Indian. People like watching fair and lovely mixed breed Indians in Movies, though there are some exceptions but not very popular.
There is a saying good looks cover a multitude of sins. This is the age where appearance matters the most or it is definitely second to talent. If Good looks can cover the sins of Pakistan, it can cover anything.
As far as humanity is concerned ,we need to be honest about including the evils and imperfections of human beings in this concept of humanity.
Therefore humanity is as disgraceful as the religious, geographical and racial differences. If humanity dies, this planet will flourish as human is the most selfish creature ever existed on earth.
So nation, religion and race have their own significance and ignoring these things is a more serious problem
