Though both celebrities have a huge platform, they admitted to being terrified of the response they would receive.
Asking somebody “Are you sure?”
can be harmful and dismissive.

Instead of asking this, validate their same sex attraction by thanking them for trusting you.
Another common question is “Why didn’t you tell me before?”
On the opposite side of the spectrum, telling somebody “I knew it!”

is a totally inappropriate thing to say.
It may seem like a fun and tongue-in-cheek response, but it actually perpetuates harmful stereotypes.
Moreover, you should delicately ask if the person wants to talk about it more.

Don’t push the topic, as this could make the person coming out feel panicky and tense.
Instead, just let them know you’re always there to discuss anything.
This will make them feel supported and secure.
