why is that anything the left wing touches, it gets corrupted or destroyed ?

Because the voices in your head say so 

They knowingly or unwittingly follow Satan.

WRONG!

America was founded by "left wing" Liberals during The Age of Reason.

America gets corrupted and destroyed by right wing CONServatives who are NOT AMERICANS!

I've been hearing this BS since the '70s. BTW, you forgot to say they're communists.

The Progressive Left HATES America and the American Constitution.  They seek Unconstitutional Power to use to Dominate you and your assets.

lmao... literally everything you listed is wrong or a straight up lie.

>overt political correctness in media

There is nothing wrong with being considerate for your fellow humans.

>forced diversity and promoting interracial couples agendas

What "force diversity"?  Encouraging diversity and giving people the same rights is not promoting anything.

>destroying statues of great men who fought for this country

Uh... the Confederacy was NOT this country.  And there is nothing great about men who promoted and fought for slavery.

>twisting and corrupting the definition of marriage 

This is probably the most stupid claim you have here.

>turning pop culture into a cesspoll of hedonisitic satan worshippers 

Nevermind, you went even stupider.

You forgot the G.I. Bill, Clean Air and Water Act, workplace safety standards, child labor laws, oh, the horror. 

In 1776, conservatives wanted to stay with King George.  It was a bunch of PROGRESSIVES who declared independence, wrote the Constitution, etc.  You would be nowhere without generations of liberals paving your way.
