Why if you suffered make others suffer?

I remember a lot Anti-antisemitism as well as anti-black comments growing up on Long Island. My father was an Irish-Catholic living in Protestant Scotland that is why he came to this country where he hoped there would be a little less prejudice and always said don’t put anyone else down for you could be next. I don’t understand people who came from ancestors that suffered prejudice could turn around and do it to others.

Who is smart and who isn’t

I know that history is filled with what really big thinkers have said about this subject for thousands of years so I think it is time for someone who just wishes they could be as smart gave their thoughts of what makes someone smart and what the hell is smart anyway.

The more education one gets the more facts that are thrown at him/her, some are able to use those facts and learn from the mistakes of those that came before us. They advance the Society they live in through their talents There are others that go through the higher education system to become doctors and even run for president of the USA, but when the talk about history or the bible they get facts that a grade school student knows is wrong. So my guess is that facts are useless without reasoning power. You have to use logical reasoning power to know which fact are probably true and which are probably false. It seems that some people have reasoning power and some don’t which brings up the question are people born with Logical Reasoning Power or is it learned as they grow up?
