In the good 'ol days.....I've read quite a few posts, but I'm not going to bother reading the rest. Young people are doing what they've always done. Pushing boundaries and upsetting old people. If you're offended by the actions of young people, you're probably the old fart you used to bitch about. Suck it up princess(es)!
Oh, OK, so we suck it up when some brainless little **** paints his friggin' tag all over our fences, or smashes our car windows, or does anyone of a thousand other mindless destructive things that seem to pervade society these days.
And if you weren't around when I was their age, you can't just say they've always done it. (and yes, I've read your later post where someone made a false assumption about your age.) Tagging was NOT done, for a start. Try walking any street in a city and see if you can avoid being confronted by childish scrawl written on every second horizontal surface. The worst sort of "graffiti" we had was bill posters.
Simply denigrating those on the forum who voice their displeasure at what the youth of today does is probably typical of what has happened for many generations. The older generation always despairs of the youth of the day - my grandparents' generation probably did it about my generation when we were young.
However, the young people of today "generally" (ie not all) convey the impression that nothing deserves respect and that other peoples' property is fair game. Police are hamstrung by "Nanny-State" laws and bloody do-gooders, who introduce idiotic political correctness into society then reinforce it with idiotic laws, which bestow rights on children to take legal action against their parents, prevent teachers from administering corporal punishment and believe in talking to kids to amend their recalcitrant behaviour when they are young.
I doubt that my generation can accept the effectiveness of those changes simply because we see no evidence yet of them working, but plenty of evidence to the contrary.
