Why do so many straight men (even good Catholic men) speak with a lisp?  I don't mean a flaming homo type lisp....but still, that somewhat weak, high pitched lispy voice?

Because they weren't in the boys' choir or boyscout?

(Seriously: years of good old singing train the voice)

"My daddy left home when I was three
And he didn't leave much to ma and me
Just this old guitar and an empty bottle of booze.
Now, I don't blame him cause he run and hid
But the meanest thing that he ever did
Was before he left, he went and named me "Sue."

Well, he must o' thought that is quite a joke
And it got a lot of laughs from a' lots of folk,
It seems I had to fight my whole life through.
Some gal would giggle and I'd get red
And some guy'd laugh and I'd bust his head,
I tell ya, life ain't easy for a boy named "Sue."

Well, I grew up quick and I grew up mean,
My fist got hard and my wits got keen,
I'd roam from town to town to hide my shame.
But I made a vow to the moon and stars
That I'd search the honky-tonks and bars
And kill that man who gave me that awful name.

Well, it was Gatlinburg in mid-July
And I just hit town and my throat was dry,
I thought I'd stop and have myself a brew.
At an old saloon on a street of mud,
There at a table, dealing stud,
Sat the dirty, mangy dog that named me "Sue."

Well, I knew that snake was my own sweet dad
From a worn-out picture that my mother'd had,
And I knew that scar on his cheek and his evil eye.
He was big and bent and gray and old,
And I looked at him and my blood ran cold
And I said: "My name is 'Sue!' How do you do!
Now your gonna die!!"

Well, I hit him hard right between the eyes
And he went down, but to my surprise,
He come up with a knife and cut off a piece of my ear.
But I busted a chair right across his teeth
And we crashed through the wall and into the street
Kicking and a' gouging in the mud and the blood and the beer.

I tell ya, I've fought tougher men
But I really can't remember when,
He kicked like a mule and he bit like a crocodile.
I heard him laugh and then I heard him cuss,
He went for his gun and I pulled mine first,
He stood there lookin' at me and I saw him smile.

And he said: "Son, this world is rough
And if a man's gonna make it, he's gotta be tough
And I knew I wouldn't be there to help ya along.
So I give ya that name and I said goodbye
I knew you'd have to get tough or die
And it's the name that helped to make you strong."

He said: "Now you just fought one heck of a fight
And I know you hate me, and you got the right
To kill me now, and I wouldn't blame you if you do.
But ya ought to thank me, before I die,
For the gravel in ya guts and the spit in ya eye
Cause I'm the son-of-a-gun that named you "Sue.'"

I got all choked up and I threw down my gun
And I called him my pa, and he called me his son,
And I came away with a different point of view.
And I think about him, now and then,
Every time I try and every time I win,
And if I ever have a son, I think I'm gonna name him
Bill or George! Anything but Sue! I still hate that name!"

Don't hate--just respond.

Can ANYONE on this thread give an example - YouTube, whatever - of this kind of 'speech impediment?'

It might provide a better angle in which to respond.  Otherwise, the topic itself just seems pointless other than being some sort of axe to grind.

Don't hate -- just do.

Could be a hearing problem which translates into speech issues.

I once read that when Michael Jackson was caught off guard his voice was much lower, he actually sounded like a man.

I think role models are important.  Try to be more like your dad and less like your mom.  Look for strong men that remind you of your father.  

If your dad isn't around enough, then try to find an actor who reminds you of him, who's made a movie that you like and make a habit of watching it.  

If your father has uncatholic morals, then try to be a good catholic version of him.

I have often wondered how a teenager can be fine and all of a sudden he is flaming gαy- with a lisp and flamboyant demeanor? Like no warning signs-  a friend's brother who was (seemingly) normal all the time growing up, and then ran into him after not seeing them for a year or so, and wham! gαy as can be. Where does that lisp come from, out of nowhere?
