Language is helpful, it betrays a person's viewpoints and their level of respect.
Mispronunciations and other triggers to start ignoring a person:
kaMAHlah
Barack Hussain Obama
EYErack
EYEran
EYEtalian
Nevahda
Nookyular
President Trump
A caveat: I was taught that the President title was for life and "former" is improper. The problem is that Trump claims to have won 2020 and addressing him as such leads to confusion. So I think the rules have changed because of his treason.
