You're right, we has this same discussion just a couple of weeks ago.
It's true though, a lot of us find it a little intimidating to be doing something that causes people to stare and point at us - it's only natural :shrug:.
My suggestion in the other thread (which you may not have read) was to wear an MP3 player, whilst you're out and about

. Provided that it's not going to make you liable to be mugged or run over by a train that you didn't hear coming, it's actually a good way to help yourself relax and to dettach yourself from the world around you. I find that people don't tend to come up and talk to me if they see that I have earphones in, whereas they do occassionally try and engage me in conversation if I don't.
I suppose that I'm lucky to be living in Germany, as people here don't seem to have the same dim view of togs as they do in the UK (judging purely on comments I've read here and not on personal experience :|).
Finally, as was mentioned in the other thread, quite a lot of people are probably a little in awe of what you're doing and are just curious in a friendly way, so you really don't need to feel like you're doing anything "wrong". I've only been into photography for a few months, so I can easily remember what I thought about togs, prior to becoming biased

...
Quite simply, I didn't know one camera from another and didn't care, as long as the person on the other end of it wasn't making a nuisance of themselves (by ordering pedestrians not to walk through their shot, or getting up in people's faces for unwanted "candids" :bang

. If you're not planning to behave like that, you've got nothing to fear and nothing to apologise for :|.
Go to it
