Don't hide whatsoever. Come out and show your support for the President. I head up a YR club in NC. But if I lived in NY or Chicago or LA or Portland, I would come out and proclaim my beliefs. NO FEAR!!
I wish I had been more vocal during my school days in NYC, but openly wearing a Reagan button the day after his 1984 victory at NYU got me a lot of evil glares as it was.
