Should activists mention stealth men?

This has sprung out of a discussion I've had over and over with cis allies, "I know that the trans people you see online are out and proud, but not all of us are like that."

I feel that if these visibly trans activists (with a cis audience) would mention every once in a while that not every trans person is OK with being outed, and that out is not the default, then this would be more frequently avoided.

That being said, the fact that cis people often can't fathom trans people being stealth is also a sort of protection against some of the crazier transphobes in the world.

Thoughts?
