As a man, I think we men all have it within us to be "abusers",
It is our upbringing, moral values, sense of right and wrong, natural inhibitions and outside influences that stop us from becoming these monsters who are around us.
I had a personal encounter with one of these characters at the age of fourteen, just started my first job and very naieve about life in the wide world!
That experience haunted me for many years afterward.
I was unable to speak of it to anyone for many years until one day while watching a programme on the subject of abuse, i was able to tell my wife.
Incidently my abuser was an Australian working over here, he was also a Catholic. and gave me a "holy candle" afterwards, saying I should not tell anybody about him. As I say, it greatly affected my life for a long time!
It is only my anonymity on here that I'm able to write this!
There are also women abusers, to whom, presumably, my comments would also apply.
