Networking is a skill beyond simple vibing and should be treated as such. For those with social anxiety, having a script/plan at least allows one to be on autopilot so they don't have to in fact give a shit.
Also introverts definitely tend to not like networking or any group activity w/ a bunch of strangers (edit: I mean tend to like the 'idea' of them, but once there, can enjoy them). I think you meant that they can do it without fear.
