I get it. I understand that you started out trying to have a simple conversation. But some of your earlier replies to other people were antagonistic and deliberately mean, which is why he replied the way he did. You can't expect to say something potentially hurtful to someone and not get a reaction.

Think about how you feel when people talk to you like that, now imagine other people feeling the same way. I know it's hard to tell when you might be offending someone but immediately going for the low blow when someone says something only creates more negative emotions for everyone. Do you want to get wrapped up in that?
