Terminator 2 (T2) is a masterclass in combining CGI with practical effect and its ending is a rare cinematic full stop.
The T-1000’s liquid metal form was revolutionary, the morphing effects were cutting-edge in 1991, yet Cameron used them sparingly and only where practical effects couldn’t work. That restraint made the CGI more impactful and has made it so they still hold up 35 years later.
The truck chase through the storm drain, the helicopter flying under an overpass, the Cyberdyne building blowing up; it was all real and you can feel that when you watch the movie. There is no way any movie studio would do that nowadays when they could just CGI giant Michael Bay explosions.
The destruction of Cyberdyne and the Terminators meant the timeline was reset. Judgment Day was averted. The T-800 lowering itself into molten steel is an iconic moment; a machine choosing self-sacrifice for humanity. It’s a perfect final note, not just for the character, but for the franchise. Bringing him back again and again weakens that sacrifice. Any sequel has to undo all of this just to exist. Which is why to this day, I have not watched a single Terminator film after T2.
Sadly, it has been going on for pretty much as long as punk has been around, and it doesn't really have a single contributing factor.
In the US 80s hardcore was made up mainly of white angry teens and young adults. Most weren't racist but some were. And the low entry of musicianship needed to get into punk made it easy to start a band, so some Nazi bands started forming. The fans of these band thought they would be welcome at other punk shows, but were wrong. That's why the Dead Kennedy's wrote the song "Nazi Punk Fuck Off".
In England skinheads have been around since the 60s but where not the racist skinheads you think of today. It was more of a working class subculture. Oi punk evolved from this subculture, so as fascist started adopting skinhead culture the music came with it. It also doesn't help that some early punks would wear Nazi symbols to be provocative, even if they didn't believe in the ideology.
Even in the 90s, when I was a teen and active in the local punk community Nazi's would show up to a show every now and then. It always ended up with them getting drug outside and getting the shit kicked out of them. Even if they weren't at the show if there was a sighting of Nazi's nearby people would go running to kick the shit out of them. Yet, every few months it's like they expected something else to happen when and would show up again.
My only thought on why this shit is still happening 30-40 years later, is that you have to be a fucking moron to be a Nazi, so it's not like they would have the best judgement when it comes to where they are welcome.
