So, here's why I must respectfully disagree: On a political board, you are inevitably going to get the following:
1. Individuals pretending to be two different groups of people fighting over different sides of a political argument, intentionally making one side (who will lash out at other users and otherwise behave unpleasantly) "lose" to make the "winner" look better.
2. Individuals who pretend to be multiple people advocating for the same idea, making it look as if many people on the board hold an opinion when they don't.
3. People who are literally paid to come and do 1 & 2. This is called consensus cracking, and the goal is to get you to side with a political stance based on personality, bandwagoning, and emotion rather than evidence.
There are obviously ways to get around the defense IDs provide. However, I've found that the people who engage in this behavior are often too lazy or stupid to figure it out.
