Is it arrogance or is it just accepting that weather is part and parcel of our job and you make sensible decisions with the cards you are dealt on the day. Maybe I've been lucky but I've flown regionally for almost two decades and never got close to severe turbulence or moderate icing or had windshear that has done anything more than trigger a monitor radar display! Sure, some challenging approaches but when sensibly handled, nothing to write home about. All a bit dull and boring really, just as it should be.
Don't confuse arrogance with a deep rooted respect for Mother Nature and many of us being a product of training machines that taught us how to make good sensible decisions and have the courage to follow through with them.
