What social taboos that exist today do you think will not be around in 100 years?
I was reading a book on social life of the upper-middle class and new rich of the American 1920s and realized so many things we now do proudly were considered socially taboo back then. This was especially the case for clothing, makeup, women in certain public spaces, etc. What do you think will be different in the 2120s? Or maybe even the next 50 years?
Eating meat. I think two things will happen: (1) we'll discover that there's very little difference in feelings between humans and other animals and (2) science will allow us to produce meat in a lab.
What? There is no taboo being vegan. You two are really trying to twist OP's question into your narrative. He's asking what is taboo TODAY, that will no longer be taboo in the future.
