Has everyone just decided that words have no meaning anymore?
Yes. It seems a lovely social media trend. And on instagram many (most?) people don't seem to actually be able to use words, only emoji's. Not sure if that's worse or better.
What if a person lives near racists, people who keep directing hate at hindus because of their (unjustified) hate against muslims? They may feel unsafe if people knew they were hindu no matter the area of the world
It's good that you don't feel threatened, but unfortunately not everyone is so lucky. And we should respect people who want to keep any aspect of their lives private.
As long as people have to fear getting kicked out, disowned, subject to slurs, or otherwise being ostracized by their family, friends, or community for being gay, lesbian, bi, or trans, then yes, the LGBT community remains vulnerable. And once you've been vulnerable like that, it never goes away. There will ALWAYS be a part of you that remembers it and it will affect you for the rest of your life.
That alone is enough vulnerability. The fact that the LGBT community still deals with a lot of verbal and physical assaults as well just makes things worse. And yes, this is still an issue in the UK, in Norway, the US, and other western countries.
