How often are we told not to be preachy about something?
Except the thing is, we should be preachy.
If we don’t talk to people about what we know and what we believe, who else will?
If you want to talk about the climate crisis, go for it.
If you want to talk about x, y, or z, go for it too.
The important thing to remember, is to not cross the line to evangelical.
