Whenever I hear the phrase, ‘We don’t need to argue semantics’, two thoughts come immediately to mind.

1. We do need to argue semantics
2. Your position is shrouded in the ambiguity that you’d prefer remain intact—even if you are unaware of the ambiguity

This might be something less, but I find that many philosophical arguments are caused—at least in part—by a lack of a common foundation.

A common response to a ‘definition check’ is ‘you know what I mean’ or ‘everyone knows what X means’. My response is, respectively, ‘I might know what you mean, but I want to be sure’ or ‘great, so this should be easy for you to provide’.
