So do they?
If you hate some one(and you want to express your hate for them) then will your actions(ruing thier business ect.) or your words(badnaami of that person in socity)hit them harder??
that is my Question!!
Depends on the person, for some people a quiet word in their ear is enough - for some people you need actions but not something as destructive as youre suggesting - man I would not even do that to my worst enemy???
I wonder if the saying
latoon kay bhoot batoon say nahi mantay implies here :D
Sometimes they do but there are people who don't understand anything but words coming out of mouth ofcourse.
I blieve actions do speak louder then wordz.. i mean its obvious isn’t it..?? “seein is blievin?!?!?” 
I don’t think it’ll b terribly hard for sumone to understand n e action unless they r totally dumm !!

Good question Desert Fox.
The answer, I suspect, is not as easily apparent as one might think.
In the examples that you have provided, actions may speak louder than words....but not to convey the message accurately.
Right out of the starting gate the person that "hates" is losing.
Next, if this person decides to go out and destroy someone's image or property, the first thing that comes to my mind is how hateful he/she is.
I don't even pay attention to who this person is talking about or attacking until much later in the sequence of events.
So the way I look at it....the person's mission does not get accomplished.
I think actions do speak louder than words, cause you can tell a person something over and over again, but until you've proved it, by taking some action, they probably won't believe it.
Like mystery gal said "seein is believin".
