NL: Why the hate on short buy-ins?

[Dennisa]

I'm happy I have the option to play full or short stack. The reason is I live in Los Angeles. If I want to practice online for my b&M play, I buy in for 20 or 33 big blinds so I can simulate casino play.

The main reason the full stackers dont want the short stackers is that IT COMPLICATES THE FULL STACKERS GAME. Its may be a small advantage, but it is an advantage to play short stack in NL.
