Various factions would like us to feel isolated and helpless so we can be manipulated more easily. All of the things you mentioned still exist and have meaning, but there are alternative meanings being pushed at us. And we not everyone has a community or family in the traditional senses anymore.

If you want to be a member of a community, you can. There are many available in most places, and there are more on the internet that are not limited by location. Find a group of people with common values, common interests, or anything else that ties you together and participate in it. Humans evolved to be social animals.

Human interconnections are a threat to the power that be. Individuals are easy to deal with via manipulation, intimidation, or incarceration. All of that becomes harder with groups, and the larger the group, the harder it is. That is also why we see so many efforts to subdivide us by race, culture, nationality, generation, education, income, religion, gender, gender preference, sexual preference. The less unified we feel, and the more we view the people around us as “other” instead of part of our community, the less able to we are to band together to form an effective threat to the ruling class.
