Another KK Preflop Situation

[d1sterbd]

PP NL 100 6 max. Villian's VPIP stat is 56%. No other reads. Is this a call or fold? Would the fact that he just called the 6 dollar raise give me any info here? This is the third KK hand I have had in the past two days in which I reraised and they went all in with decent size stacks.
