Temper Went Boom!

I have noticed over the years my temper is calm until I get pushed to the brink of no return. Sometimes it takes a comment from an ignorant individual to push me off to nor return. Unfortunately that .001% happened today and I feel like Muhammad Ali ready to bust some chops Street Fighter style . Yes it is that bad I had to use a video fighting game. I have yet to figure out how to tame this emotion and make it go away. Stupid people irritate me so very much.

So far I have tried putting it out of my mind.
Breathing
Doing other things
Any suggestions besides time?

And yes I have entirely blocked this person out of my life as of 1.5 hrs ago.
In case you are wondering the comment was an ignorant generalization about heritage.

Yeah that's tough. I have a temper that can go from sweet to bitch in a nano. I have to be seeing red to become physical, rarely has that happened, but when it has I have been pushed beyond beyond, and I become someone completely different. And strength that could kill an ox. People who are ignorant, not like they are not book smart, but ignorant in their line of thinking...narrow minded, don't think out of the box, too set in their thinking, etc.? Have no time for either. My reaction to them varies, but either way they will know by the time I'm done either A) keep your stupid comments to yourself, or B) I really don't like you so stay away.

The one thing I have really had to teach myself though is that everyone has an opinion. Whether we agree with them or not doesn't matter, it's how people go about it. If you can agree to disagree, or be open minded to where they're coming from but still know that you have your own beliefs, makes it easier for me. (obviously there are things in life a person can never agree too, so yeah, there's things I wouldn't waste on second of my life listening to someone's reasoning in their thought process of why). Also their background, way they were raised, who they are outside of that 'thought or attitude'. I avoid those things with them if I can see generally they are good people, but if they're assholes generally or they like to continue to push their views? Pushes my limits.
