I think the boards should say, so long as discussions remain civil - ie, don't smear entire groups of people for being on a certain side of the aisle, liking a certain politician, etc. Criticising the politician him/herself is one thing or criticising/pointing out the flaws of an argument, but I've seen a fair bit of attacks on those who simply support certain politicians or belong to certain political tribes.
As much as I can find the content tiresome and sometimes even depressing, it's also a nice outlet to get my feelings and opinons out there, of which I really don't feel comfortable doing in life, hardly even amongst my own family and friends. So it is an outlet in a certain way. And I think it's the case for many as well.
