I do not like random people talking to me, if they know they have a different view on something than me. IMO she should not have spoken to you in the first place if she did'nt expect a reaction. What would you say if someone said any of these to you while minding your own business:
"I don't like the car you drive"
"I don't like your hair, shoes, jacket, glasses, skin color or anything else" It is none of their concern, I don't have patience for those people at all, they are usually just trying to get you wriled up.
