I think the younger generation are very aware of perceived racism, my daughters always correct me if I say anything that could be thought of as racist, usually inocently. Also, older people do tend to speak loudly, my great aunt, in a restaurant, tended to remark on the other diners in a very loud voice, which was extremely embarrassing.
That sounds rather ageist.
We were out to lunch with friends the other day. There were two other groups there, all 30 or 40 somethings, both groups very loud so that we could hardly hear ourselves.
Perhaps older people might speak loudly because they are deaf?
