I know @feoh personally, and I can definitely say that it wasn't his intent to state this as an indisputable fact, and certainly not mine either.
Given that the website has chosen to use English, it seems fair game to offer constructive criticism of the choice in words. This isn't an attack of anybody's personal views, their culture, or _their_ word choice.
To wit, your point is about this project consisting of many contributors and users across the world is well made. My first language *is* English, so I'm trying to offer some alternatives which, as a native English speaker, I know are richer descriptors than "sexy."
Hopefully these word suggestions can start a constructive dialogue.
