Racism is bred through ignorance Erith. It does not get filtered out down through generations unless it's taught out.
There's nothing childish about it in the slightest. He's a public representative...he represents our country. His job is to know better. There was nothing non-sensical about his remark. He knew full well what he was saying. He was just too much of a gobshite to realise he was going to be in serious doo-doo afterwards.
Just because he's from an older generation does not give him the excuse to make these sort of faux pas. This is the 21st century. If he wants to sit at home and shout at the wogs on his TV then that's his business. Maybe that's where he should be?
Imagine your point, if I'm seeing it correctly, in a different scenario. Imagine a senior member of a company's staff making a derogatory remark about an immigrant in front of other senior and junir staff in his company, or at an AGM. What would happen to him?
