Truth is, that "true socialists" are as easily corrupted once they attain power as anyone else, and once they are corrupted and powerful, then the truth could be potentially dangerous, and well, then the lying begins, the biggest lie will in their case be "I am a socialist" which nearly everyone believes, and well there you go. I mean when you've seen how many cold hard irrefutable facts Trump regarded as "fake news" you learn to see things in a bigger picture, as I cannot call Trump a socialist (and on one thing he's honest. He doesn't even pretend to be). Once people have power, they fear to lose that power, and the truth can make them lose power
