According to this article in the Telegraph, a study in the US has shown that swats (or as the British say "smacks") produce better citizens. The study was based on the answers of 179 teens.
Those who had been smacked up to the age of six performed better in almost all the positive categories and no worse in the negatives than those never punished physically.
I can't say that I am really surprised. Yet liberals and those who would shrink parental rights are only likely to be angered that the study didn't show what they wanted instead of rethinking their beliefs.
This is one of the reasons that I do not support the UN Convention on the Rights of the Child (UNCRC) and encourage you to look at ParentalRights.org.
Take a look at what is going on in Malta because of the UNCRC. According to the article, "Any provisions in the Maltese statute book that allowed corporal punishment and that could endorse child abuse had to be removed in order to come in line with international law, according to a British expert." Notice how (in the minds of these folks) international law takes precedence over the will and law of the Maltese people.
In Europe, there is a growing movement pushing for a ban in all countries. Nineteen European states have legally barred physical punishment in the home and another four are committed to doing so. Malta is one of the remaining four that has not taken any such steps.
