Acronyms are not destroying English. Acronyms are simply shorter ways to type out phrases. Stating that acronyms are the root cause of words being misspelled is crazy and simply untrue. Most acronyms contain short words such as "be right back, laugh out loud, talk to you later" etc. Most people already how to spell those words and no one uses acronyms in day-to-day conversations. Without acronyms it would take a tremendous amount of time to type some things out and it is pointless to do so when it can be typed out in three letters or less, therefore they are very useful.
