I'm looking for a way to idiomatically express the sentiment that just because you give something a different name, or precede it with a disclaimer, it doesn't change what it is, e.g.:
- "I mean this as constructive criticism, not an insult, but …"
- "I'm not racist, but …"
- "With all due respect …"
