Couple of things.
Way back when men were men and bikes were steel, it was fashionable to set up handlebars so that the ends pointed at the rear axle. The current style is more likely to have the bottoms parallel with the ground.
Now here's the interesting part. There is only one person in the whole world that your bike has to please. Frankly, I think that you should experiment with the tilt of your handlebars until you find the position that you like best - it's easily done. Then leave 'em there and don't pay attention to anybody's comments including mine.
If you start fiddling with handlebar tilt because somebody else told you to, next he'll have you removing stem spacers, using different pedals, wearing a different jersey, criticizing your socks or handlebar tape color, etc. etc. etc.. Do you see what I'm getting at? The fashion police are NEVER satisfied NEVER rest and are NEVER in doubt that they're right. I think that it takes the place of sex.
