a/And yet you couldn't understand what I mean.. whatever.
b/Yes of course I do understand, otherwise why would I bother to repeat the word, once with a capital letter to boot?
To further calm your qualms - I did read about what it mean to be culturally Deaf, capital letter Deaf, and so on.
c/ may I point out I haven't said "I am"nor "I deserve to" only "I feel". For all the good it does, I may feel like a penguin or a kite, or a Barbie doll
- so what? by definition, "feel, feeling" is state of emotion, or belief, granted to anyone.
But I will answer you, no plm 
- how do I rationalize I am both? well for starters I do am deaf, as in I can't hear.
Even with my HAs I can not hear like a normal hearing person does, I do have serious limitations. Hence, deaf.
Now, reading about the struggles the culturally Deaf has endured and are still enduring - these are very familiar to me personally.
A lot of these struggles I experienced personally. A lot of matters I understand. A lot of matters I support.
Some I don't, but show me a community where everybody down to one single person agree to a "t".
while I do not know ASL, I do know some single simple proper signs. For times when I am out of my HAs I use my own invented
signs -so, in a way I do "sign", too. Hence, Deaf.
Keep in mind, please, I have not said "I am" - only that "I feel".
