Richie- it depends (standard answer).  I probably am a reactor on some occasions in that I jump right in and act. 

I react in my head or I vent to an uninvolved party.  Otherwise, I usually respond.  

The assistant to a lender commented on how calm and quiet I was being in light of a terrible situation they caused.  I advised her that quiet is the silent sound of rage. 

It depends.  

Why?  Because Roger D. Mucci likes it when I respond that way and because it's true especially in this question where more information is needed.

I respond.... I'm a logical kind of person and reacting is to me just emotional.

 Good Sunday morning Richie. It depends upon the situation. Typically, I  respond.

The nature of your question is begging for an essay response to respond to your question.

Between Michael Jacobs and Roger D. Mucci I think I shall leave this one alone 

I like to take some time to think out a situation to see what would be the best decision.

I usually have a reaction first but settle down and then respond after I have had time to think it through.

I believe that I respond  --- at leat I try not to react quickly.

Richie Alan Naggar I'd say, as much as I want to 'RESPOND', I end up 'REACT'ing!

I am trying to get over with my 'last minute' habit - and have been successful, to an extent I must say (or else I would have been answering this question at 2 AM EST....lol!)

Depends on the issue, but usualy I respond.

I try mostly to respond as it gives the thought process time to react and my Irish temper in a reaction might not be as nice.

Richie,

I like to think that I have plenty of equanimity.  I do react if one of my own is hurt.  A

Richie,
I would suggest we all react inside. I try to keep the reaction inside and respond on the outside.

Some of each, I'm afraid.  Though I'm at my best when I anticipate and am ready to respond.

I am a "responder".  Reacting is emotional.  Responding is a rational response.  I generally don't speak when I am tempted to react on an emotional level.  I think about it, try to consider the other persons position, then respond accordingly.  

Depends on the situation and how long I stop to think about it before I do either.

Good morning Richie. Most of the time I would respond, but on a rare occasion I would react.

I do not react nor respond if I'm upset or have not enough information. I focus on finding a way to fix the situation peacefully. If the situation requires a quick reaction, I can be quite fast and efficient. 

What's up? Something happened to you? Tell us!

I do what is appropriate depending on the situation.

Depends on the situation. Mostly respond, but good to have quick reflexes to react, verbally as well.

Real estate professionals always need to be responsive. 

I respond.

I have more to give, Scarcity is not my realty.

When the reservoir is depleted, when there is nothing to give, reaction comes to the surface.

It is helpful to know that when you are face-to-face with a reactor.
