The letter "U" is ruined!

It has now reached the point where I can no longer stand the mere site of a stand-alone "U". Whenever I see it, I think of all the people who use it in the place of 'you', and I want to scream. I can understand minimal abbreviation, such as TX, FL, NC etc. for the states, I can even undertake (on very rare occasions) to use "lol" when it is fitting, as an expression. But when people begin using '2' in the place of 'to' or 'too', 'R' in the place of 'are', 'Y' in the place of 'Why', and (most specifically) 'U' in the place of 'You' , that is just plain unbearable to me. It is denigrating to the English language and derogatory to the gifts of speech and communication. : (
