Making fun of non-native speakers' mistakes is so cool, it makes you look very clever.
Thats just like your opinion or whatever. I care about professional results I'll meet people half way with their communication.
I speak Spanish poorly. If I were running a company and creating a website or marketing materials I'd hire someone fluent in the target language to proof my material.
