1 Yes! Despite official records which claim that I am an old, overweight, white man, I am clearly a Japanese school girl!  Here, let me find a picture of myself in my school uniform...

2 I think I don't want to see it. (Shades of Sailor Bubba!)

3 I should try that line on my doctor next year when she wants to do a prostate exam. "Gender is a social construct; there's no vas deferens between male and female!"

4 That deserves today's Scarecrow Award for punsmanship.

5 I think I swiped that from the "MASH Goes to New Orleans" novel.

6 Tell the truth, Steven... you got a jump on this a long time ago.

7 I'm not bald.

8 I, however, am now thoroughly traumatized.  Where was my trigger warning on that?

9 Males (XY) who think they're female, females (XX) who think they're male, humans who think they're vampires, werewolves, or dragons...

I consider them to all be the same thing.  And I'd love to see people start calling "transgender" people "otherkin".

There are actual cases where the chromosomes don't match the sexual phenotype.

One case of that is a mutation which prevents the testosterone receptors from working properly. If that happens in a person who is XY, they have a female phenotype (although they are sterile). But this is extremely rare.

Lefties don't like to admit it but the majority of transsexuals have serious mental problems. There are people who get sex reassignment surgery and feel much better afterwards (for example Wendy Carlos) but I read that the suicide rate is disproportionately high among those who do this.

11 I should mention that cases like the testosterone mutation don't result in people who feel uncomfortable in their bodies. They grow up socially as female and usually only learn about their genetic issues when adult -- if they do. I saw a program on TV about a woman like that and she only learned that she was genetically XY when she was married and had trouble getting pregnant, which is impossible for someone with that mutation.

12 The great horror of Political Correctness is that it actually institutionalizes hatred of those with issues.  For all they claim to "celebrate diversity", if you took the same approach to Alcoholism, they would force the government to provide a keg of beer a week to them.
For the "transgendered", with the exception of the rare genetic mutation, they're people that have something very wrong with their body & mind, that's been warped & twisted into self-hatred.  They've got the highest suicide rate of any sub-group (less depressed, alcoholism Men with a loaded gun in their hand), which is the biggest sign for something being deeply wrong.
The further problem is, now, the same "science" that thought Frontal Lobe Lobotomies was the best medical recourse now says, "you're fine! we'll even mutilate you for a price!".  People in deep distress will latch onto any available option for stability, and our society now willingly gives them their own destruction. 
We've already seen this play out with Homosexuals.  The numbers are becoming a lot more clear on them.  Congenital effects against Sex Hormones (more noticeable with Males, given the rate increase for every Son a Woman has), viral load, compromised immune system & compromised endocrine system.  Like with Autism, pre-1950, most with the highest likelihood would have died from childhood diseases.   
This understanding explains a whole lot of the interactions & reactions.  It's why they invented a Strawman about the horrible treatment homosexuals were supposedly all being subjected to in the West.  (Any historical look shows it wasn't the Christians that caused the Homosexuals much issue.  You have the Socialists to blame for all of that.)  
So we now, as a society, are supposed to "praise" people for highly predictable physical disorders that may or may not effect their ability to work.  (Which is a really stupid bar to set, but it's the one they use now for mental disorders.)  Since you're not supposed to offend anyone, you get effects like the article linked.  Most everyone is a follower, so they'll follow along.  And what they're following will shred our societies apart.
I'm not looking forward to the next round of civil wars in Western countries.  It's been 150 years.  It could be a lot messier next time.

13 It's an in group/out group identification mechanism. You make willingness to assert something a marker of your group identity; The crazier it is, the better it functions as a marker, because people not in your group will naturally refuse to agree with it. If acting on it has harmful consequences, even better, because it becomes a better test of group loyalty.

Then, if you get power, you can then make asserting the contrary a crime, and thus establish the supremacy of your group, and officially suppress the out-group.

I think that's the best way to understand, for instance, punishing refusal to treat SSM as real marriage, or continuing to identify Bruce Jenner as a man. (A man who's going to be nude on the cover of Sports Illustrate, BTW. Short your stock!) It's a way for 'liberals' to identify their enemies, and attack them. That the positions they're demanding allegiance to are objectively insane only makes it work better for this.
