Stonewall was 1969. That’s fifty four years. The shift in attitudes is not that much younger than the dismantling of Jim Crow laws. To me, bigotry against gay people is as offensive as racial bigotry.
I’m actually not a fan of a lot of pride stuff because to me it smacks of empty gestures and corporate PR, but that doesn’t change the message it sends when you very visibly decide not to participate.
It is to me too. Let me say that first, lest anyone think I am arguing that what Provorov did was right, or that bigotry against gay people is acceptable. It is not.
But I don't think it's fair to say the civil rights and gay rights movements were on anywhere near the same timeline. Stonewall was the beginning, not the culminating Supreme Court decision that validated gay rights. The equivalent of the dismantling of Jim Crow laws (Brown v Board 1954, Loving v Virginia 1967, etc.) is instead Obergefell v Hodges, which was in 2015. Maybe Lawrence v Texas in 2003 counts, but that is still pretty recent. A full generation younger than civil rights.
Public opinion about LGBT people has changed rapidly (in the right direction) since then, but it is a newer shift in attitudes compared to racism.
