It's also okay to have opinions about language of course. I just often see people confidently stating, that they're speak the right way, and those others (from that other city, country, those young people, those poor people, those black people, etc.) speak the wrong way. And it often boils down to either ignorance about how languages actual work and evolve, or just elitism/classism (or worse).
And as somebody who cares a lot about languages, this just rubs me the wrong way, and I see it so often.
Hence my previous response, pardon the snark:)
