A green with a small g is someone who is environmentally friendly or concerned about the environment. An environmentalist. Green with a capital G though refers to a member of a Green party. According to Wikipedia
Green politics is a political ideology that aims to create an ecologically sustainable society rooted in environmentalism, non-violence, social justice, and grassroots democracy.
Either type of green/Green is welcome on this site, so long as they’re also a geek. Again, according to Wikipedia, a geek is
an expert or enthusiast or a person obsessed with a hobby or intellectual pursuit
though it says there’s also the pejorative meaning of
peculiar or otherwise dislikable person, esp[ecially] one who is perceived to be overly intellectual
I don’t think there’s anything wrong with being peculiar and it’s not possible to be overly intellectual, and worrying about whether or not people like you is very ungeeky.

Is breaking a window an act of violence?
The Wikipedia entry could have been better, perhaps – surely all political ideologies purport to desire social justice.
Yes, they all purport to desire it, but only the Greens really mean it. All the rest of them are lying. And perhaps because some people think Greens only care about plants and animals they feel they need to emphasize that they care about people as well.
