As sociologists point out, many expressions/idioms end up changing over time. "Gay" is certainly an example of that - it has changed just in my lifetime, and very recently, in historical terms. It's only been a few years that "snowflake" has become a derogatory term; it definitely wasn't when any of us were growing up!
Unfortunately, even though Lara didn't mean it as a put-down, it has become one to many of my LGBTX friends, because they do experience people stereotyping them as 'weird' - which they are not. They are bankers, doctors, chefs, brokers, teachers, et. al.
So just as I am sensitive to comments made about PoC, I have to acknowledge that my LGBTX friends are sensitive about also being stigmatized as "something different."
I've been a member of the SF for years and never found any members to be deliberately mean or insulting - EVER. Thank you, Lara, your explanation is appreciated and understood. You are quite correct that term has been used for a long time. But I think we need to acknowledge times have changed, and we need to change with them - if for no other reason, than to be courteous and kind to one another.
