Really don't understand how it can be offensive to call a TG a bloke
[..]
Same if you were born a bloke no amounts of woman's clothes hormones or lopping bits off will change that your still a bloke albeit one without a penis
I'm using your post for illustration - this question applies to many people:
How do you define a person's sex and why do you use that definition?
It might seem a silly question, but please think about your answer because it's a lot less clear than it might seem.
Here's a quick overview of the problems with various answers:
1) Birth. This appears to be the answer you're using. It's obviously a silly answer if you give it a little thought and it contradicts reality in a spectacularly obvious way. Nobody is "born a bloke". Everybody is born as a baby. If you want to remain consistent with your obviously wrong argument that everyone is always the same as they were when they were born, you must argue that everyone is always a newborn baby for all of their life. It's a spectacularly ridiculous line of argument to be making.
2) Genes. Simple problem with that definition - genes are just data. They are not a person. Genotype is not phenotype. It's very obviously possible to change some aspect of your body without changing your genes. For example, my genes don't give me a hole in my earlobe but there is a hole in my earlobe. That hole is really there - I have an earring to prove it. Also, more directly relevant to this subject, it's possible for someone to be born with XX and be born male or to be born with XY and be born female - genes are at most plans and things don't always go according to plan.
3) Primary sexual organs. OK, at least this one is based on actual biology at the relevant time. Seems like a better bet...but this definition would make anyone who has them removed sexless. Some people have their testicles or ovaries removed for medical reasons, usually cancer. Are those people
really sexless? Also, this definition would require you to view all post-op transexuals as neuter, not as their previous sex.
4) Secondary sexual organs or other characteristics. A definition that can get rather undefined (what is a secondary sexual characteristic, exactly?) and which in any case requires you to view transexuals as being transexuals, i.e. as changing or having changed their sex.
I don't think any definition is accurate enough but I'll pencil in (4) as an acceptable definition for daily use.
