That depends on what YOU consider hiding.
Should a transsexual person personally verbally state that they under went surgical procedures to swap their genders upon first meeting a person or persons?

it sounds unreasonable to me. Thats like random people demanding to see my drivers license, or birth certificate.
Even a trans person will tell you "I'm not hiding, this is who I am" so sometimes they dont feel obligated to tell you shyt because with the surgery and hormones they are now physically the female or male they always were mentally, emotionally, spiritually.
Trans people know they have to have "the talk" with people. "The talk" being "I was born a male with a penis and now I'm a woman."

reading some of the comments in hear, some people don't even want to hear the talk.

maybe thecoli and people in general have turned a new leaf and are unbiased, more accepting and inclusive of diversity.
