The legacy of the 1960s includes an end to the McCarthy repression, advances in women's rights, Black rights, Chicano rights, ecology, gay rights, and opposition to US wars. We have good reason to thank the activists of the 1960s for their heroic struggles for justice. Your point is false, the arrogance of the intelligencia in bourgeois society did not begin or end in the 60s. In addition that arrogance does not come from smoking pot, its origins have more to do with the prejudices ingrained by capitalist society.
