I am very guilty of doing this, and it seems dependant on the subject being discussed. Certain things just flip the wrong mental switches, and it doesn't matter who it is who brings up the subject that flips that switch - or how much we love them when we're being rational.
I've learned to try to keep that response under control with Mohegan, but if it happens when I'm already upset or angry about something else, she's learned to just tell me that I'm being a jackass and walk away until I cool off.
This is my family. It may be little, and broken, but it's still good. Yeah, still good.
