what do you mean "we"?

I've been thinking how to talk about disagreeing. Arguing. Criticising. Guilt tripping. 

Someone asked a while back "why environmentalists don't talk about population" and many of us responded "which environmentalists? I do"

Our language is clumsy with its single YOU, though we could bring back THOU. But English never had different WEs for
1) you and I (sorry thou and I) and
2) Us lot (unspecified probably) 

So it's easy to manipulate our feelings and polarise us between US and THEM.

So as this is the personal is ecopsychological - do I talk about population? 

Would I try and dissuade someone considering a third baby? Difficult. But so is questioning friends who fly several times a year. Challenging allies who drive their dog to the riverside in their SUV for its walk. 

I'm trying to do it though, just by raising the issues and then trying to listen, being less attacking.

And do "WE" support coercive measures to limit population? Well we aren't coercing flyers and drivers and general overconsumers are "WE"

The way to curb population growth is by empowering women, educating girls. And free access to safe appropriate contraception and abortion of course. 

So lets practice constructive disagreement.

This is getting a bit incoherent, probably it's two posts scrambled together. I'll stop now. And hope somebody argues with me :-) Please.
