Because being part of the choir really ain't my bag, I only tend to comment in this community when I disagree with the community's CV. (and since I mostly agree with this community, that means I rarely comment.)

But when I do, I usually first try to establish that I'm not a troll by prefacing my comment with something to establish my liberal credentials. For example, I may say something mean about Rick Santorum.

Then I'll start writing about why I disagree. Then I come back later to see if anybody responded, and without fail, several people have troll-rated me.

This happen ALL the time in this community, and it reflects extremely poorly on it.
