Too Many Firewalls

Firewall: is a network security system that monitors and controls incoming and outgoing network traffic. A firewall establishes a barrier between a trusted and an untrusted network.

They say that the world is more connected because of technology but what of all the firewalls that exist? In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic. In matters of the heart, firewalls are also created until a stable relationship is established. We may smile and agree, but we may be hiding behind our firewall subconsciously. A firewall establishes a barrier between a trusted and an untrusted network.
Until we feel safe and trust what we're involved in, firewalls instinctively come up to protect us.
We communicate on the internet and that places a firewall even before our subconscious firewalls go up. How are we more connected with so many firewalls put up? And what can we do as a community to establish trust? Trust is fundamental to a relationship, how is trust built on distant communication without feeling the various firewalls that are up?
