Future taboos

We look on times gone by and are shocked at how things that would be
outrageous today were ok then - airing racist attitudes, smoking in
front of kids, drinking and driving etc.

I often wonder what things are socially acceptable today will shock
future generations. Some starters:

Dressage
- making horses dancing a sport

Home aquariums
- building tiny fish tanks into furniture as a novelty. Generally not
respecting living creatures because they're small/mute

Separate Paralympics
- I bet both Olympics will come together and it will seem strange
they were ever apart

Red hair prejudice
- making fun of 'gingers'

Mental health generally
- calling people nutters, people having to keep common issues secret
for fear of exclusion etc.
