I get triggered really hard when somebody (usually a manager) tries to end The Language Discussion saying "It's just a tool!".

I mean, the point is valid, it's a tool, but as any tool it has a huge impact on the end result. If you give a professional wood crafter a drill from Lidl/Walmart, you will worsen the end product. If you give a rookie a highly advanced CNC machine, you will not get any product at all.

A tool must be suitable to the wielder and to the job, and not having this discussion means working against both.
