Markness,
You remarked “I think that a man can’t survive if he is not part of the group.” On the material level, we are all certainly surviving much better as part of our societies, interacting with others electronically and in person, than we would be in an area without other people. On the psychological level, we need (at least everyone I’ve known needs) interaction with other humans, even when we are adult.
Individuality within genuine fellowship is possible here in America and, I’m pretty sure, even in more collectivist countries of Europe, where there is freedom of movement and association. If you are subject to a mandatory period of national service, such as the military draft, then yes, for that period, individuality is more seriously compromised.
I’d be careful in supposing the enormous numbers of people who disagree with you over such things as altruism, self-reliance, taxation, government enterprises, and supremacy of the society over the individual, do not respect individuality at all and are entirely set against rationality. Listen to all they say and consider all they do.
It can be painful to have one frustrating discussion after another with acquaintances all around you. Nietzsche wrote of that pain in the late nineteenth century. He was of a personality who liked to have lively, real-thinking discussions with people he met, but usually it was hopeless. It was like they were coming from different planets.
You may find it enjoyable to try to contact other people in your area who have some friendly interest in Ayn Rand’s ideas. You might have to put out a personal ad saying you are in search of making the acquaintance of people with that interest. If they are just too rare there, that would be one more incentive to change countries.
I don’t know how old you are, but from nineteen on I had a lover, and it was an age of two against the world, and we had each other as sanctuary. Here’s hoping.
(I’m sorry if my writing is hard to understand.)
