Well, these years were a complete mess. My depression increased to crippling levels, I lost my programmer job, I started receiving psychotherapy, my girlfriend had dumped me (as she said, "It is too painful to be with you"), I moved from dynamic languages like Ruby to static languages like C#, I found that hint of the way to improve my psychological status lies in stopping self-objectivization by the intelligence criteria (in other words, "allowing myself to be dumb"), I slowly began the process of re-joining the society, and I think that I will manage resuming usage of this site without panic attacks.

Sorry for all people who had wrote me and I did not respond. I'm truly sorry.

No, those are not exact opposites, and there are many ways to make them work together.
For example, imagine communist country as some sort of mega-Google company. Every "stareholder" (citizen) has the right to use free education (in company's schools and universities), right to use free health care (in company's clinics), et cetera, et cetera. Company's regulations prohibit having two shares for one shareholder, thus all of them are equal. All children born from two shareholders get a share automatically. All capital goods are owned by company, and all people that live in company's land are working on the company.
Isn't this company a communist country made by liberal means? ;-)
