reb e, that’s correct that there’s a strong tzad not to be concerned with what people do as a result of our keeping halacha – we do what we are obligated to do, and if people go off, it’s not our responsibility – because we’re only doing what’s obligatory on us.
that has nothing to do with making a sacrifice of letting people fall away because we want to bring out the best in others (the example of not teaching chasidim to be jewish in their dress, etc..)
