Better jump on it while you have the chance because you may go back to your unsure life. Oh shit that's an outlet everyone has been waiting for! Whether it's racist connotations, owning the libs, patriarchy, freedoms and rights. Unsure of what they are doing, unsure about their job or their own beliefs but when it comes to social justice!. Everyone is walking around kind of unsure of things. Getting free reign to exert an action like this can feel freeing since there are not many opportunities where people feel 'right'. Almost in the same way people will jump on anyone and grind them into the dirt for anything remotely racist.
It's like a 'social diamond'–people go crazy when they find one that they can latch on too. There can be this feedback loop and pressure, even if the person coming out isn't sure they are ready, sometimes the person 'helping' them can want that person to just come out so everyone can celebrate and feel like they're doing the right thing. She also notes that for the people doing the cheering on, they can want that righteousness just as badly as the person who is coming out wants to feel accepted.
