I miss the old ways too:
1) When everyone knew where to pee. IF a transgendered person used the restroom, a very low profile was kept.
2) Father/Daughter dances. Being done away with because they aren't "inclusive" of those with two mommies.
3) Common freakin sense
4) People would have laughed at the concept of "triggers", "micro-aggression" "gender identity"
There are more. These just off the top of my head.
