You’re saying the great thing about the early internet is you could be sexist and racist without being called out? I thought the great thing about the early internet was the experimentation and discovery on consistently evolving technologies and ideas with like minded folks, but to each their own.
No, the point was that criticizing someone else wouldn't get you wrongly accused of sexism or racism (as it commonly does now), simply because everyone would be able to see the accusation as absurd (it is logically impossible to discriminate on the basis of information you don't have).
Back then people online weren't really sexist or racist. They were really nice and helpful people. No extreme right. The internet was a really friendly place.
Although back then it was also kinda taboo so they were usually banned everywhere (not just online). Which was great IMO.
Not very much later of course came the masses and the emergence of awful platforms.
