Then why are you trying to defend Churchill. You are trying to paint everyone was racist, Hitler would have come to power, we would have been doomed. Churchill was racist that is that.

> It doesn’t make any sense to judge people by the standards of society decades later. If we did that we would have nobody left to admire.

Depends on who judges whom. As they say terrorist is another martyr. For British people he is great savior for us he was responsible to death of millions. As someone said "If we start wiping out parts of our history that are unpleasant we won’t have anything left"
