1. POSITIVE IS THE NEW BLACK
2. ASK ONE QUESTION, OR EXPLORE ONE ISSUE
3. MAKE YOUR POINTS ACTUAL POINTS
4. WE NEED TO OPEN DOORS, NOT CLOSE THEM
5. AVOID 'SOCIETY THINKS X'...
Avoid it, unless you can humbly and legitimately show that you have an insight that we haven't yet seen or discovered.
If one makes a huge statement like 'Society thinks X', or 'Post moderns believe Y', or The World say Z', my immediate questions as a listener are: Is that really true? And how do you know? And how has this preacher become an expert in culture and society?
There are, of course, ways to moderate cultural assessments that don't have hubris embedded in them. Show your 'working out'. Saying 'It seems to me that...' is very helpful. Or trying reading someone else's quote about society and interact with that. There are many ways to critique and pull apart culture in ways that we will believe you. That's better than pronouncements.
