B)The good old times for most of our hippies were the 1970s. Their ideals include love, peace, freedom of self-expression, and nonconformity to society’s rules. Against the background of speeches, reports, slogans, which served as a smokescreen for corruption and moral crisis, hippies showed to young people an alternative to all that. Unfortunately, now the hippie community is becoming a place for really hopeless characters and those without any ideas and principles. Is is not so difficult to look like a traditional hippie: a pair of worn-out blue jeans, long hair tied with bit of string and a couple of decorative chains. This is often used by drug sellers. They have noticed that if you are wearing your hair long and your jeans are old, you have a much easier time on the road. Remarkably, while in society at large the drug problem is becoming more serious, within the hippie community it has stopped growing. Today hippies are more socially active. They set up environmental groups and long charity projects. «Everything that brings people together is good; everything that draws them apart is evil. Love is the most powerful thing that brings people together.»
