"Animal" is a supercategory that incorporates "pterodactyl", but the two aren't the same, luchog. You have just admitted that they are NOT the same thing, even if one, according to you, encompasses the other.
Nope, you're distorting the issue.
"Gender" means either Gender Identity, or Gender Role. It does not mean "sex", and never has, despite your claim. This entire thread, and the two related threads, are clearly and explicitly about Gender Identity. Your refusal to accept that is just more indication that you're not interested in clear and honest debate, but only in scoring Internet points.
But I get to define the words I use, just like everybody else. Notice how we often ask each other how the other defines a certain word in order to clarify the conversation?
The English language, like most languages, have commonly-accepted meanings for words, many of which are dependent on context. In order to promulgate clear and effective communication, we have things called "dictionaries" that standardize the accepted meanings of words in their proper contexts. Requests for clarification are done when the context is unclear, or when a word is being used in a way that does not conform to any standard definition applicable to the context.
In this context, applicable definitions are clear. The accepted response to using a word or definition that does not conform to it's context is to use a different word or definition that is applicable.
Re-defining words to have non-conventional meanings as part of a debate indicates either ignorance of the language, or is a logical fallacy used in an attempt to support a position that cannot be defended using evidence and logic.
Oh, I'm sorry. You're not offended. Someone, somewhere may, at some point, get offended because I brought up genetics.
And I would care about this why, exactly? Are you confusing me with someone else again?
Where? I always make it very clear when I alter what someone posts. If you think I've done otherwise, then you should report it to the moderation, because it would be against the rules.

Fine, from now on I will do so without giving you the opportunity to correct or retract.
No: I DISAGREE that it is marginalising. You are assuming your conclusion.
And you're wrong. It has been repeatedly demonstrated by multiple people how the language you use marginalizes transpeople. You attempt to evade that fact by redefining the language rather than admit error. Again, words have commonly accepted, context-dependent meanings. Your consistent refusal to acknowledge that is rather odd.
Where have I made that claim? About the "genetic defect"? It is one by definition. Just like albinism which, also, does not make someone "defective" or "wrong".
Albinism has distinct health effects, and can be traced to a particular gene mutation. That is not what is being discussed, and doesn't work even as an analogy. You're resorting to non-sequitors again.
I think you cut off your sentence, there. Due to what?
Due to natural variation in human development; which may be genetic, epigenetic, or some other factor not fully understood yet. The science, which has been linked to already, indicates it's most likely a combination of the latter two, as twin studies do not show a distinct genetic propensity toward transgenderism.
It's amazing how you accuse me of redefining words without ever commiting to a definition yourself.
I have, your refusal to acknowledge standard definitions and context is not my problem.
However, according to Encyclopedia.com:
And:
So how was I redefining words, exactly?
Remember what I was saying about context?
Already posted multiple times. You're refusal to acknowledge them has been noted. You post your sources, and I'll post mine. And by sources, I mean actual science, not random, out-of-context encyclopedia entries.
Making an ice-cream cone isn't, either, but then neither are what I was refering to.
Wait, what? You said your claims were supported by science, now you're claiming that science is not what you're referring to? I think you're seriously confused here. How does this non-sequitor even come up? I'm kind of curious what bizarre logic makes that make sense in your mind.
