I think there would need to be intention (at least logic dictates so)
I can definitely agree with this. I'm sure no one would want to intentionally stumble someone else, for example constantly offering a drink to a recovering alcoholic. However, when it gets to the point that one feels the need to look over their shoulder when buying egg nog or easter candy at the market just because you like it for fear that a brother or sister will come up to you and say could stumble someone, I think that is going too far.
