It doesn't actually matter what you think. What you shouldn't do is be rude or belittling to others.
Mind you, there are famous stories of bad-tempered unsocialised auks. One such would ride alongside a complete stranger and start a 'conversation' about how that person's frame was too small/large, saddle too high, wrong tyres, etc. He's been punched on the nose at least once in response. Nice enough bloke when you get to know him. He posts occasionally here.
