I looked it up, I still don't really get it

one is more sexual than the other

I looked it up on Google and I discovered that transsexual and transgender are actually spelled differently

I never had the urge to look it up...yet. But I have known some trannys in my time, the entertainer kind doing Pricilla Queen of the Dessert type stuff. Mostly ABBA and Gloria Gainer stuff.

You do know I was being facetious, right? lol

Yeahhhhh...me toooooo. Heh heh. The direction my google searches have bin goin lately, a guys gotta be careful. You only google dog porn once.

Yeah!...there's a lot of hazy areas where the definitions of those two terms are almost identical.
Think of it as book titles. A book on trans-genderism would be titled A BASIC INTRODUCTION TO THE SEX CHANGE MINDSET.
A book about trans-sexuals would be blatantly titled: STEPS TO CHANGE YOUR SEXUAL ORIENTATION NOW!

I think one changes parts and the other just "feels" like the other gender
