Okay I get that ! But in the case of the ICE both are actually acceptable.

I.C.E sounds good so those ICE. I guess in this context as some else said, it’s because they are “ice cold” (in this context).

Would it be acceptable in a conversation to talk about the I.C.E ?

Funny enough… I do say S.Q.L or U.R.L 😅

ICE=Immigration and Customs Enforcement

FBI=Federal Bureau of Investigation

USB=Universal Serial Bus

None of those are words :/ but an acronym.
