How do you experience peer pressure or group think (if you do) on fluther?

I hope that no one experiences this, and everyone feels free to speak their mind at all times. Yet, I think, even in the most open and welcoming groups, there will be people who feel like there are in-groups, or pressure to respond or think a certain way. A subtle group norm can be established without even people being aware of it. If that’s the case, what kinds of issues or posts do you experience that pressure, and how do you experience it?
