If muslims were forced to compensate for every killing they have done for the last 1400 years, there won't be a single muslim left on earth. Every strand of hair, every teeth and blood will be used to repay the world for their ignorance, bigotry, racism, slavery, and genocide.
The United States of America was created after exterminating the native American Indians who lived there for many thousands of years before the arrival of the Europeans. Christian missionaries played a large role in the extermination, and people such as the "blessed" Junípero Serra single handedly wiped out entire ethnic groups (such as the Tongva). Does that mean that some one should kill all the Christians using whatever means available?
The only way in which that piece of trivia is relevant is that it shows how extremist/delusional your overall mentality is. Most (if not all) of the people responsible for killing the (real) Americans are long since dead, and modern US people don't carry responsibility for the crimes of their ancestors. If you disagree, then that would mean that you also carry responsibility for the crimes of your ancestors, even if they hid behind the "USSR" mask.
In some countries, people with a criminal history can have their criminal record erased after a certain period of time so they can re-start their life without ongoing discrimination by vigilantes. The same should apply here and this thread is ONLY about getting justice for a crime that's new and relevant.
