SMS(short messaging service)is bad for Standard English.Agree or disagree?

I think I agree because SMS is to make shortcuts example(hw r u).Actually it is how are you but people use it in shortcut.So, follow my idea as it is the bestf.

It also can make people's english bad.Instead of proper english,it become singlish.I use shortcuts when I am lazy but for exams,I use good enghish.
