Really, idk what u seen or what happened with you. Just wanna say that, The dogs keep barking, but the lion does not retreat.
In this strange world you will find many types of people, you can't change them. So learn how to ignore them. Just do whatever u wanna do here, what others says that doesn't matter.
No, we are not equal or the same. If we were then we would all look and behave the same. Migration is bad if you have no intention to assimilate to where you are relocating to. Very bad to have a community of different people who all want and believe in different things and follow different cultures and traditions. Under a democracy it just makes too many different groups all fighting for control of everything. Homogeneous society is much simpler to govern over. If you're going to move to a new country, be prepared to assimilate and become a part of that country and it's way of life, do not bring your country into the one you're supposed to be joining.
