I don't really want to see a bunch of politics on the forum. Having said that, "No Politics" is the most political thing one can say. Freedom of speech and whatnot... But this forum isn't really the public square, so we AHA members do have the right to regulate what's on our forum.
The trouble with just saying "no politics" is that in this country its hard sometimes to say what politics is. The government is involved in every facet of our lives, so it makes it hard at times to discuss something without being perceived as making a political statement. For example, im not sure nowadays that it would be appropriate to discuss how many bathrooms a tap room should have...
It seems to me that discussing beer and brewing related issues, even on the business side, should be allowed so long as candidates, officials and political ideologies are avoided, and that inflammatory comments are not allowed. A peaceful discussion about how much a brewery employee should get paid should not be banned. Or polite civil discussion of environmental impact of brewing, or ingredients issues, etc.
The bottom line, however, needs to be the advancement of homebrewing and preservation of this great forum. A healthy combo of being considerate and thick skinned might cure most ills.
