You may not like the use of acronyms but they developed for a reason, as stated below, and are now part and parcel of social-media culture. For many, it is not a problem and if it is, for you, there's no obligation to use them.
But to imply that people are lazy, or that the use of acronyms has somehow created a nation of children and adults who are illiterate is offensive.
The reason that quite a few have difficulties with grammar and spelling is because of the way English was taught in schools many years ago. The accepted system was changed and it resulted in problems with spelling and grammar for many who had to learn what they were not taught.
The acronyms are quite useful for those who are using a smart 'phone with a tiny keyboard, and many do on here. It took me a little time to get used to them, but there is a list below and I soon became familiar with them. I can type almost 80 words per minute - but it is not all about me.
I can spell, and speak the King's English. Neither my children nor grand children are "illiterates", even though they also use acronyms when sending text messages to me.
You don't care what other people think? That's indicative of a closed and haughty mind. You've been on here a few weeks and want to change the way people communicate because it doesn't align with your way of thinking? Worse, you imply that people are lazy and / or illiterate because of it. Your comments are goading.
