I get it. It's just too much trouble for you to choose between multiple ways of saying something in order to be succinct instead of vague. People who don't value clarity never realize that they people they're talking to - every time that happens - value that communication (and the person attempting it) less and less over time.
What's so hard to understand? This forum is full of people correcting others' poor use of communication when talking about everything from natural selection to global warming to employment demographics. Someone makes a sloppy choice of phrase, and the simple thing they're trying to convey turns into a four-step back and forth during which everyone from trolls to the merely dim decide to screw up the thread or just rant because the OP couldn't trouble themselves to just speak clearly in the first place.
This particular lapse in clarity, which comes up regularly in lazy science and technology reporting, isn't the point. The larger point is the grinding erosion in careful communication, and the erosion in clear and critical thinking of which that is an indicator. You think this is about ego? It's about understanding the power and value of properly nuanced communication, especially in the shortened format that venues like this tend to encourage.
I need to learn English? What you're really saying is, I need to forget English, because it's just too much trouble to quickly sort through the differences found in several ways to say the same thing, each of which contributes to a more quickly digested communication of different ideas. You're cranky because I'm not a fan of lazy thinking, and the fact that you think "learning English" means forgetting how to distinguish between different words is exactly the larger problem I'm pointing out.
