Lol you are pretty uneducated as your post proves, i doubt you are actually from the uk. Why speak about something you have no idea about? I'll clear up some of your misinformation so people dont get the wrong idea.
1. Australia was never a penal colony as Australia (the country) didn't exist up until 103 years ago.
2. Most of the crimes comitted by criminals sent here were petty crimes, such as stealing a loaf of bread. They were hardly scum bags, infact after most of them did their jail time, they help setup colonies and were a great part of society. Many of the prisoners were educated people, school teachers etc.
3. Your decedents are not convicts, they are born free. If you comitt a crime and you have a child, would they be a convict? No, that's just absurd and proves up stupid and delusional you are.
4. Only 1 million Australians out of 22 are actually decedents of convicts, so your false implication of "we are all decedents of convicts is wrong.
5. Another absurd statement by you "criminal traits passed down by generation" This is the most absurd of them all. Actions you take in her life are not genetic and cannot be passed down. If you murder someone, that wont make ur son a murderer.
As i said, before you make silly, uneducated and absurd statements, think twice. It may stop you from looking like a complete moron.
