What's the inverse of rose-colored glasses? Looking at the past through the lens of today? That's kinda what this comment suggests. The internet of the 90s was much safer than the internet of today is.
This has nothing to do with internet. There were assholes long before the internet who would bully whoever looks weaker. They would do it in person, on meetings, in friends group, against students if they were teachers, against waiters and other service staff. This guy definitely seems like one.
