Ok, here are my opinions on these, for what they're worth.
1/ abortion should remain a womans' right
False. I believe that abortion is the intentional murder of a human being and no-one has the right to commit murder. as a "choice".
2/ war is wrong regardless of the circumstances
False. While war is never a good thing and is always a tragedy, it is a fact of life in this world of insanity that we live in. As long as governements exist, and people remain basically as they are, sometimes war will be the only means of resolving differences between these governments. People never start wars, governments do. If one country commits a criminal act against another country and this can't be resolved through diplomatic channels, then war my be justifed in cases such as invasions.
3/ prison is the best solution for the rehabilitation of career criminals
I'll have to go with a True and a False on this one. I don't believe prison rehabilitates very many career criminals. It is, and should be, a punishment. Personally I believe that anyone who has been repeatedly imprisioned for habitual crimes should simply be kept there and away from the general society. A person makes a choice as to whether they are going to go out and knock someone in the back of the head with a brick so they can steal the 20 dollars they have. Some people simply belong locked up.
4/ any couple who are in love should have the right to marry
This has been such a touchy subject of late, with the media furiously fanning the flames. Personally, and this is my OPINION, I do not believe the governmant should legitimize an unnatural and perverse lifestyle. Again, this is MY opinion. I don't really care if two men or two women want to sleep together or live together or whatever, that's there private business. But I do see this as perverse and do not think it should be given a legitimate status.
5/ poor parenting is responsible for the majority of juvenile crime
True and False again. While poor parenting may be responsible for a lot of juvenile crime, poor parenting basically meaning lazy parenting and setting poor examples, at some point responsiblity has to be laid upon the person who commits the act. There is far too much time spent on trying to find "reasons" for people's actions and in some way removing the responsibilty from them. Sorry, I believe that a person should be held accountable for their actions regardless of the "reasons" behind them (bad childhood, too much television, whatever).
