You are not ">logic" greater than logic. You obviously haven't met anyone ever.

People who look trustworthy are con-artists. I bet that a lemon car dealership has the most trustworthy looking people working there. You can't tell someone's gender by looking at them. Come to America sometime and we will amaze you with technology.

You can only see what other show you. The medium of how they show you is irrelevant.

This is really just run of the mill paranoia. Society gets scared when people can have secrets. On the internet you are not subject to your local community judging you/ The internet is social relief. Some people abuse that. However, this can be countered by following simple common sense. I don't go telling everyone where I live the second I meet them, do you? You run more risk from anyone you meet in person than you do with any you meet online. People online can't just decided to beat you to death and then do so. Even identity thieves still prefer to go through your garbage than through your inbox. I don't understand all the fear. People probably need a better education as to what real threats are.
