I've known women who could perform just as well physically as most men. I've also know men who couldn't perform physically any better than most women.
The fact is, men will generally outperform the women.
But the issue here is what is the percentage?
I for one will never say that there are no women that can perform physically at the level of men. However, the question is what percentage of women that can, and what is the effectiveness in trying to find that small percentage.
Think of it as simple economics. Is it more effective training 100 people with an 85% pass rate that is all male, or 100 of mixed genders where only 60% will pass? And assuming 25% will fail for physical injuries, that is now 1 injured permanently in training as opposed to 4 permanently injured. How much do we devote to finding the small percentage that can perform at that kind of level for that kind of period of time?
I myself, I see it as a waste of resources, and a distraction to the actual mission that the Infantry has.
Consider this. At this time, there are no major Football, Hockey, or Baseball leagues that are either co-ed or female only. The closest we have is the WNBA, but this is still an exception. Not a single female has ever played in any major porfessional sports leages (not mentioning the publicity NFL instance) since they have been founded. In fact, I would like to know of more than a handfull of women that have played in such sports at even a college level, let alone a high school level.
So yea, go ahead and demand that the military do away with such "segregation". But first, let's see how the world of professional sports handles it. Demand that all College and Professional teams bring in females along with the males.
And for those that bring in segregation, realize that professional sports started to desgregate before the military did. By the time that Ike signed an executive order demanding that the military desegregate, the sports world had already been doing that for years (sometimes decades). So let's spin this the other way. Demand that women be placed onto pro sports teams, and see what their record is like.
In fact, let's make it simple. Demand that each top team in each league place 10% women on their starting rosters. They see after a few years how well that goes.
I am not one to ever put down the women's sports teams like the WNBA. But put the player sof the LA Sparks on the LA Lakers, and do not think for a minute that their playing will not suffer. And that is only a game after all, not a case where literally life and death is in the balance.
