I like DISCUSSING politics/national issues and hearing what others think about topics, but I hate when people just stereotype, snipe, and regurgitate their party or their chosen media outlet's talking points.
Some of my favorite political posters are those who are typically on the other side of the issue, but actually discuss the issue, post their own opinions and thoughts, and read and respond to my questions and comments. They usually teach me something about the issue and make me reevaluate or readjust my stance.
