I disregarded the claim of “racism”, because at the time, it was not an issue. Instead the official reason was turbans and beards, which I will take at face value, even though they are stupid reasons.
Nor will I criticize Reagan. He just took bad advice from the military command.

21 Indian Order of Merits (roughly equivalent to the US Medal of Honor), 14 Victoria Crosses (same), multiple citations for gallantry and heroism.
Now your turn. Please cite how they “weaken the US military”. You seem to really have a down on Sikhs, so why is that? All the Sikhs I met in the military, and in civilian life, seem to be pretty respectable people.
Reagan wasn't told what to do, the ex-Army captain did what was right in regards to telling the Sikhs to go military or move on to other work, Obama agrees with you.
I asked you ""I would like to see your numbers for all those claims you made about the GIs who practice Sikhism."" as you keep using Sikh political activist sites, you didn't show me those numbers.
"In the US military, as enlisted they typically advance to senior NCO, and as officers, to higher ranks, though they have been excluded from flag officer ratings.
In the US military, they tend to prefer Infantry combat arms, in elite units if possible, and Medical Corps as physicians. Their competency in either is unchallenged.
Excluding them to me is like excluding Methodists, except Sikhs tend to have better motivation and drive."
