As someone who remembers both decades, I think the 80s were worse than the 90s for intolerance of the 'wrong' political opinions, and both were worse than now for general intolerance of the 'wrong' political views, though the most extreme are worse now.
I remember being occasionally shouted at and sneered at in the 80s, both by Thatcherites for being left-wing, and by left-wingers for not being left-wing enough. It hasn't happened to me recently, though maybe it's because I'm in a different age-group.
I remember all sorts of arguments between different groups of feminists as to how feminism should be pursued: there was one extreme shade of opinion that one acquaintance held, that all men should be castrated and their sperm frozen for use by women to be able to reproduce (presumably embryo selection and/or selective abortion would ensure that only girls were born).
At the other end of the scale, a student journalist reproduced an unflattering picture of a woman speaker about feminism, and captioned it: 'Would you rape this woman? The unacceptable face of feminism'.
And it wasn't just a matter of some students being crude. There was no legal concept of rape within marriage until 1994. Even in the rare cases where men were prosecuted for rape, they were often acquitted because the victim had 'asked for it' by wearing revealing clothing. When one rapist was convicted for raping a hitchhiker, the judge let him off with a fine because the victim had shown 'contributory negligence' by hitchhiking in the first place. While rape cases still rarely result in conviction, and there are still obnoxious stereotypes about rape victims, I don't think a judge would be able to say quite that now.
To go back to censorship, Mary Whitehouse was still very active in the 80s. She absolutely frothed at the mouth over some swear words in 'Brookside' and tried to use the blasphemy laws (yes, they still existed until 2008!) against the films 'Monty Python's Life of Brian' and 'The Last Temptation of Christ'. While this particular sort of censorship outcry was less common by the 90s, Section 28 forbade (at least as interpreted) any acknowledgement within schools of the existence of homosexual relationships.
What is worse now is the opportunity to hound people through social media.
