If:

There were no people of color, they'd pick on redheads.

If there were no redheads they would pick on people with glasses.

If there were no people with glasses they’d pick on fat people.

If there were no fat people, they’d pick on welfare recipients.

If there were no welfare recipients, they’d pick on non-Christians.

If there are no non-Christians around,  they'll pick on Catholics.

If there are no Catholics around they'll pic on Christians from any denomination except theirs.  

If there are none of those around, they'll pick on college graduates.

Obladee, obladah, yeah! Yadda yeah, the list goes on...

(The same thing applies with Non-Christian bigots. Just change a word here and there.)

Bigots are bigots
No matter what the name
The underhanded tactics
Are all just the same.
They are heartless and evil.
That’s the name of their game.
They are social criminals and
Look for someone else to blame.
