It's not just Jains (it's almost all Hindus as well), and the original Swastika [1] really doesn't have anything other than a positive connotation. It's considered to be an auspicious symbol, something which brings luck, prosperity etc. Even now if we buy something big (like house/vehicle etc.), the first thing religious Hindus do is get the ceremony done for making it 'auspicious' (by a Hindu priest), and drawing Swastika on that property is an important part of it. The people in US, if you visit any famous Hindu temple there, you might observe a priest doing the same ceremony with someone's new flashy car.

The symbol is also used in almost any important life event in Hindu culture.

Even if they think Nazis' symbol is bad, ideally they should easily be able to see the difference between that and the Indian symbol which is almost always red, vertically upright, and with four dots.
