<human>: Provide a brief overview of the text.

My girlfriend and I were at Starbucks today in a wealthy suburb close to where we live. After ordering we sat down next to a table occupied by two wealthy-looking middle-aged women having coffee. We were talking about something trivial when I overheard one of the women next to us mention "Obama" and the other respond with "...well, I want to shoot him... I probably shouldn't say that in public, but..." It wasn't a joke per se, but wasn't said seriously. Still, I froze and lost my train of thought. I tried to keep listening and caught something about his speech on the Middle East and the "horrible" things he said about Israel. (Don't want to make this into an Israel/Palestine thing, just trying to provide context.)

I felt like I should have said something, but I just couldn't. Obviously these two rich women from suburban Milwaukee aren't conspiring against the president, nor would they pose any meaningful threat if they were. And they have just as much of a right to their opinion as anyone else. Yet I was seriously taken aback to hear adults talking about killing the president in such a cavalier manner and have been thinking about it constantly since it happened, feeling guilty for not offering a piece of my mind.

I want to think that I would have felt the same revulsion if it had been 2006 and I heard people talking about wanting to shoot George Bush, but maybe this is just my inner liberal sissy talking. Am I foolish for even giving this a second thought? Or should I feel guilty for not telling them to take their disgusting conversation somewhere else?
<bot>: Heard two women talking (unseriously, from how it sounded) about wanting to shoot Barack Obama over his stance on Israel and didn't say anything. Should I feel guilty or am I overreacting?
