I dont post in political threads so much anymore. It gets tiring to post a somewhat reasonable (IMO) post and have it get lost by the people screaming at each other.
Plenty feel the same way. I definitely get annoyed when someone trots out an old falsehood (i.e. Ronald Reagan's approval ratings), I post the same correction with links and all, and then I get ignored. 2-3 pages later, same thing shows up.
