I don't much care what the tube announcements say.
If there is a tiny group that feels hurt by "Ladies and Gentleman" I'd prefer to ignore them. Not because I'm bigoted. I just believe that sometimes people need to grow a spine. Life is routinely hard. If you've got time to worry about the wording of a tube announcement, you've got it pretty good.
Ladies and Gentleman is an all inclusive phrase because is was created in good intentions. It covers everyone. Not all women are ladies, not all men are gentleman. They are not qualifiers of gender so much as conduct.
Traveling across town last weekend the Tube was full of rainbows and glitter as people travelled to Pride. An elderly couple got on. I gave up my seat for the Lady. The Man remained standing. I nudged the girl next to me to jump up and let him sit. She looked at me, then looked the opposite way.
It was a microcosm of the whole damn issue. She would have jumped off the tube and started chanting or singing about the oppression of any number of marginalized groups, yet couldn't get her bum off a seat to let a pensioner sit down.
Bottom line, we can make arguments for inclusivity all we like. But there are assholes on all sides of every issue.
For what it's worth "Hello everyone" doesn't bother me. I'd just have rather seen it rolled out without any announcement or fanfare or press release. It shouldn't be seen as a 'Win' by any group or movement. Because it's not.
