"I don't think anyone will look back with fondness or positivity towards a bunch of drug-pushing, mentally stunted adulterous freeloaders that disrespect hard working people, people putting their lives on the line for their country, people devoted to their families, and the nation that allows them the freedom to exist in the first place--while jerking themselves into a froth over who's the edgiest edge lord."
Even as someone who favours liberal drug laws at this point, the social upheaval of the late '60s had objectively horrific consequences for the poor in particular. The massive drug epidemic that to this day kills more Americans than the entire Vietnam War every year, the unprecedented doubling of murder rates overall in nearly every Western country from 1965-1975, and collapse of the family unit seem like more tangible downsides than a small number of what you describe as edgelords jerking themselves into a froth on a forum read by other edgelords.
Nearly every major social issue of the late 20th century exploded as a direct result of hippie culture bringing drugs and hostility towards the family and social institutions into the mainstream. People often think of rising crime as the result of the 1980s crack "epidemic," but the explosion in murder rates occurred almost entirely from 1966-1975 and actually grew at a slower pace up to 1990 (outside the UK): https://datawrapper.dwcdn.net/uRI8Y/1/ The US murder rate in 1974 was exactly the same as it was at the peak of the "Crack epidemic" in 1990, and more than double the rate it was in 1964.
You can still argue the benefits outweighed the costs, but it's simply ignorant to pretend 1960s counterculture was some uniformly benevolent movement for peace and love, any more than the movement you identify with 4chan is merely a benevolent movement for "national pride" or "family values."
How 4chan specifically got designated the "counterculture" in this thread is questionable, but so is the inability to look beyond the status-quo, contemporary perspective of major media, academia and corporations.
