Fact: Racists support Hillary. Sexists support Obama. Both support McCain.

Allow me to teach the people unfamiliar with logic a simple lesson.

A implies B is does not necessarily mean B implies A.

Usually, we use a little arrow to mean "implies". It looks like this: -->

If I write A --> B, that is a logical expression that means (loosely) "If A is true, then B is true", or put more succinctly, "A implies B".

I can also write a similar expression: B --> A. This means - you guessed it - "If B is true, then A is true".

Now, here is the important lesson. There are certain circumstances when (A --> B) =/= (B --> A). I used the =/= symbol to mean "not equivalent to".

Replace "A" with "One is a racist" and "B" with "One will support Hillary or McCain".

Or Replace "A" with "One is a sexist" and "B" with "One will support Obama or McCain".

What this all boils down to is the following statement in plain english:

A racist will support Hillary or McCain, a sexist will support Obama or McCain, but that does not mean one who supports Hillary is a racist, nor does it mean one who supports Obama is a sexist.

Super duper bonus lesson!

An idiot will support McCain. And a McCain supporter is an idiot.

We write the above using the "equivalent" symbol: ===

"One is an idiot" === "One supports McCain".

1. There's no point in trying to teach DUers logic. Especially when you can't do it correctly yourself.

Quantifiers are required - not optional - to model your boldfaced statement.

2. I seriously wish schools required that students take a logic class in high school.
Most people need it.
