That teacher should have been fired. You don’t pressure people to come out. They may have their own reasons for not doing so, like not being certain, not having a supportive family, working in a homophobic environment or maybe they just don’t want to be around obnoxious social justice warriors.

My sister used to be like this. She suspected I was gay when I was 17, and would urge me to come out. Because she was "such a good ally". Then my mother ordered her to stop doing that. My mam knew I wasn’t ready. So my sister backed off. My sister is a lot better with it now, because she’s come out as bisexual a few years ago and realises that sexuality is not something people should wear on their sleeves or make a fuss about. She respects my wish to not make a huge deal out of my orientation. But that was after boundaries were laid down.
