...because people don't fake injuries to get out of a PT test/event that they know they're going to fail. Give people an out, and there are always people that will take it. Will it matter? Depends on what kind of a force we want, pretty simple. That can be argued by both sides, by the way.
I have no problem with people arguing the point on what the country should do with this issue based off their desires for 'equality' or our American values (even if I agree or disagree), but don't try to tell me that this change is needed to make the military operationally stronger/more efficient (cost/risk vs reward). If that is your argument, then there shouldn't be cutoff ages for UPT (I'm sure there are plenty of people in the mid 40's could make it through UPT), we shouldn't be kicking people out who continuously fail their PT test by only a minute/10 sit-ups, kicking people out of programs/the military who continuously fail academic tests by a few points, etc. Why does the AF require certain ASVAB scores/a HS diploma to serve?--I'm sure there are people who don't make the entrance criteria who would make great Airman. Why aren't we letting guys wear nail polish or earrings right now?--what does it hurt?
As for tellng the CC "Iidentify with gender X"...will this need to be confirmed by medical/psych personnel at all? Will people be able to one day say they are gender X and the next day tht they are gender Y? Will there be any repercussions if it is suspected that people might say this to have different PT standards (just one example)? Will the military now pay for active duty folks to get gender realignment (or whatever it is) surgery? Who will make the call on whether the surgery is warranted/approved? What if special prescriptions are needed for hormones, etc? What if Dave says he wants to start wearing earrings tomorrow and gives the reason that he's identifying with the female gender...does he have to get a wig or is he allowed to keep his high and tight, but can also have the ear rings?
Again man, it's cool if you support this idea/proposal based off your morals/ideology, just don't tell me that it's needed to make us a stronger fighting force or to make us more efficient. This is all about ideologues changing the culture of the country, and as more often than not, it starts on the large scale with the military since its done by fiat and not by the culture changing on its own. Is this a good thing--do the end justify the means? I oubt it, but i guess time will eventually tell.
Oh, and a horrible argument comparing this to desegregation (see two paragraphs above). I'm not aware of black Americans needing anything special to serve (hormones, different PT standards, surgery), other than for people to get over their bigotry. Learn to make a better argument if you want to convince people who are on the fence/think differently than you do. I'm all ears if you want to make that argument by the way.
