> my wife really likes that show, but I haven't gotten in to it

It is not a question.

In many countries it is illegal to ask question about sexual orientation, religion, marital status, age or even race. Assumption is that such information could be only used for discrimination. If someone would be compiling list of gays at my old workplace, I would probably call the police.

Disclosing sexual orientation to close colleagues after couple of weeks is fine. Scarfs and other sings are also fine. Proactive disclosure at inappropriate moment (job interview) would be probably interpreted as harassment (hitting on someone), same way as saying to woman "I am straight". People who organize gay parades etc.. are perceived as extremists who milk public budget.

I hope I explained it well without sounding homophobic.
