nobody except losing players complain about it being "rigged". Any player who tracks their hand history will see that the statistics always stay the same and even out. Not to mention, humans are hardwired to remember negative emotion over positive ones (according to the APS it takes 5 good memories to every one bad memory to even out emotional response). This is an evolved response because negative responses can result in death and we are learned creatures. So when people scream "rigged" I usually just forward them to a poker strategy website so they can learn how to play their hands properly.
