BAs are definitely not less respected by normal people. By petulant nerds who get their rocks off by talking about their BS degrees, maybe.
The real difference in a BA and BS degree is that one is related to science and the other is not.
BA and BS degrees are academically and professionally equivalent. The denotation of your degree means a whole hell of a lot less in using that degree than... actually using that degree. Certain courses of study may be more challenging to some, but that doesn't mean people with BS degrees are any better or have any better shot at a job outside of their specific training.
When deciding upon what type of degree you want, and what course of study you'll pursue, I advise against focusing on what makes you look smart. Focus on what you would like to be doing in 10 years and then pick what'll get you there.
