You haven't been following legislative efforts in recent years. Safety peaked several years ago, and has been rapidly declining since then.
Also, there's no need to insult other users.
I forget what the stat was in 1999 but it is something absurd. Like 90% of the US was against gay marriage. In 2022, 71% were pro gay marriage.
I am gay and when someone says bullshit like this is just drives me crazy. As if a gay person in high school today can possibly relate to my experience of being gay in high school in the 90s. It is such an ignorant statement and view.
I really doubt there are statistics to back this up. More likely, the number of people consuming rage-bait (drawing attention to the worst) on social media such as reddit has done up.
Without such social media, an asshole yells abuse in a store and it ruins the day of 20 people in earshot. With social media, it gets uploaded and viewed by 20,000 people.
How many have you seen? How many have you 'seen' on social media?
As for laws, I really think you're missing the bigger picture. Anti-LGBT people had the law on their side a few years ago much more than today (and accordingly, they had less reason to protest.)
I am not based in the US, so i might lack context.
