Why are latches abhored in Programmable Logic Synthesis and Analysis tools

Transparent latches are apparently not present in FGPAs and creating them out of multiple computational logic elements somehow results in loops.

Why exactly are latches hated?

Besides this, I wanted to know as to what things does a buffer encompass. Is it just a D-flip flop or a tri-state element? tri-states do not have a memory as far as I know. Than how are they a buffer?

    I never expected this question to be so hard, or is there something else wrong with it?
