it's not like the risks for adults are completely nil. Not everybody thinks it's worthwhile to be martyred for their sexuality (I mean that in a literal sense in many cases...). The implication here is that somehow grownup gays have passed the age at which the public will harm them for their sexuality.... OR that they SHOULD PUT THEMSELVES IN HARM'S WAY, like it's their duty as grownups to lose their jobs, their social network, their family, etc. as a result of their sexuality.

This is a good point and I agree, which is why I am not out as bisexual offline. But perhaps it is different for people on the public stage. Maybe they won't lose their jobs so easily. I guess it depends on what they are doing...
