Will sensitivity training help Marines adapt to homosexuals openly serving without affecting combat proficiency?

I must say, I am still in shock that your brothers and sisters admitting that they attracted to a person of the same sex may change your overall opinion of them and make you or them uncomfortable to serve alongside of. People are starting to request for transfers or to be separated from this said person because of who they love.
First off, don't we all go through the same training, the same rigorous training?
Don't we all bleed the same color and we all are raised in the same aspect of hoping we succeed in life?

Why, all of a sudden, does it change the persons entire persona and allow others to criticize or mock their way of life?
Personally, I have had many friends that were homosexuals. Some that I have served with, yes. Many of them are still my very close friends to this day.

If the Military and Military members would stop degrading persons with a different love interest and just keep their noses clean, we wouldn't have to discuss this nor would any homosexual service member feel the need to hide or feel ashamed.
If you don't want to know the answer or if you don't agree with it, why ask?

Sounds to me like another power point presentation the military is going to use to CYA. Just like SHARP, EO, Suicide, etc. etc. After the training is over, if an incident occurs, they can say they trained maries on how to be sensitive to certain issues. Power point presentations don't fix nurtured dislike of homosexuality nor do they fix racism. They also don't prevent suicide, sexual assault, or harassment. That graph circling around about 80% of our jobs being classes on these type of issues is becoming more and more true.

CPT Jack Durish Acceptance of homosexuals varies widely in society. While military members may be less apt to voice an opinion about it one way or another, a person's own preconceived notions and ideas are going to have more to do with whether they adapt to serving with an openly homosexual person than any training the military uses.
