Being afraid of stuff, so that one avoids rather normal encounters is not necessarily a healthy thing. There have been people who have been mugged, who have retreated into their own homes, refused to go out because they might get mugged again. This of course can be a bit debillitating.
It can be normal to have some fears, but there can also be a certain satisfaction to over-comming them. When I was a kid, I was rather afraid of heights. One day I wanted to see something (was away from home) but it was up several flights of stone steps (in a given monument) with a railing at top that over-hung some view. I wanted to look, but as I said. In the end, I ended up forcing myself to go up them steps (first time just a couple, then a couple more), but I made it.
Since then I've done some rock climbing and stuff (OK, no 90 degree propelling), and it's actually rather enjoyable. But I would have never known if I was unwilling to face my fears. Something similar happened when I was a kid, and a bunch of friends of mine played down in the sewers and what not. I wanted to join them, but was uneasy about it. In the end, I prodded myself along, little by little...
But as has been mentioned, it is a free country and people are free to go to or not go to the movies with whomever they please...
