A few words on the matter.
To the Politically Correct Brigade:
Disallowing a Garda from incorporating a turban as part of his uniform is not "racist". Sikhism is not a race. It is a religion. Therefore the word you are looking for is "bigoted." It must be said that I am inclined to share your annoyance on this matter. However, I am a pedantic sod and I would like if you would argue coherently.
To the Armchair Republican Brigade:
If a man wants to join the Garda Reserve and be of service to the community, then by all means allow him. Through his actions he has shown more desire to improve this country than most of you self-righteous 'patriots'... It must be said that this nation's penchant for culturally inbred colloquialism does grow exceedingly tiresome. Do you even know why you're objecting? Really?
The lad could wear a flowery pink stetson and a Rangers jersey for all I care.
There, I've said my piece.
