As a kid, gay people were practically lepers.
Eleven Years ago, Dave Chappelle just outright said "gay sex is just gross, sorry it just is", and it was considered funny and acceptable. (Not harping on him specifically, just pointing out what it was like in 2004)
Seven years ago prop 8 passed, if barely with some caveats about lack of understanding.
And now? SCOTUS upholds gay marriage and it's socially reprehensible to mock homosexuality. It's a strange and very positive feeling watching a country's world view shift like this.
